The Samuel Roberts Noble Microscopy Laboratory (SRNML) is an organized research unit at the University of Oklahoma. As such, it is under the auspices of the Vice President for Research (VPR). The SRNML has been established to provide a University wide resource and facility. Its use by as many members of the University community as possible is strongly encouraged. Access to the SRNML and its microscopes is open to all potential University users who have a need for the facilities in their research, either sponsored or unsponsored. Use of the SRNML is limited to faculty, students, post-doctorates, research staff and visiting scientists at the University of Oklahoma as they pursue their research and/or creative activity. The SRNML is not available to individuals or companies not affiliated with the University of Oklahoma, unless their work is performed by University of Oklahoma researchers on a contract or grant administered by the Grants and Contracts office.
The SRNML is located on the second floor of the Animal House, the building between Richards Hall (Zoology) and the Botany/Microbiology Building. The SRNML also occupies two rooms in Botany/Microbiology. Entrance to the SRNML is easily achieved from the second floor of the Botany/Microbiology Building or from the stairs at the northwest corner of the building.
Currently, the SRNML houses transmission electron and scanning electron microscopes. Among the microscopes available for use are:
The SRNML darkrooms are equipped with the standard darkroom items including:
In addition the following items are also available for use:
Membership of SRNML Advisory Board: The Advisory Board will consist of six faculty members appointed by the VPR after he/she consults with the SRNML Director and other interested parties. Each term of appointment, subject to one re-appointment, will be for three years. Terms will be staggered such that two new members will be appointed each year. The representation on the Advisory Board will be as broad as possible and will at all times include one faculty member each from the Departments of Botany/Microbiology and Zoology plus faculty from four other departments who are likely to have users of the facility.
SRNML Technicians: The technicians are employees of the SRNML and thus, are supervised directly by the SRNML Director. Their primary responsibilities are first maintenance/repair of the microscopes and other SRNML equipment, secondly training of instrument operators and then aiding individuals in their microscopy research. They are not permanent research technicians for any individual researcher, so no researcher should expect to receive preferential help from them. Overall technicians' responsibilities include:
With respect to point (5) and (6), it is emphasized that researchers who need to use the SRNML on a routine basis should become qualified operators, so they can be responsible for most of their microscopy needs.
SRNML Users: Any faculty member, student, post-doctorate, visiting scientist or research staff at the University of Oklahoma may be a user of the SRNML. Users fall into two categories.
Qualified Users: To become a qualified operator, a researcher must be certified by the SRNML Director that he/she is qualified to operate a particular instrument. Certification must be obtained for each instrument separately. Qualified operators will be classified as follows:
Instrument operators will be assigned to one of the above categories for each instrument by the SRNML Director on the basis of his/her experience and demonstrated ability to operate the instrument. The SRNML Director may designate one or more SRNML technicians or members of the faculty to test and recommend certification of potential operators. A list of the names of the qualified operators will be posted in the SRNML.
Training Courses: In order to train new operators in the use of the instruments and other facilities of the SRNML, the SRNML staff and its associated faculty will offer instruction and training of various types that are designed to meet the varied needs of potential users of the SRNML. All training courses must be approved by the SRNML Director. The types of instruction will include (but will not be limited to) the following:
Loss of SRNML Privileges: Until certified as a qualified operator, a user should not attempt to personally use an microscope unless he/she is taking a training course and is being directly supervised by an SRNML technician. Use by a non-qualified operator will result in loss of use of the facility.
A qualified operator, who is observed by an SRNML technician or the SRNML Director not following proper protocol, not correctly using the microscope or using a microscope for which he/she has not been certified, will have his/her qualified status revoked. If the user wants reinstatement as a qualified operator, he/she must again be certified as qualified.
SRNML Schedule: The regular hours of the SRNML will be from 8:00 a.m. to 5:00 p.m. Monday through Friday (7:30 a.m. to 4:30 p.m., if the University is on that summer schedule). The facility will be open at other times only to qualified day/night operators or by special arrangement with the SRNML Director.
Instrument scheduling: In order to permit as many researchers as possible to use the instruments and to help researchers plan their time for using the SRNML, a sign-up sheet for the use of each instrument will be posted at a designated location. Scheduling will be done on a weekly basis. If scheduled maintenance/repair or if time for training is needed on an instrument, time will be blocked off on the sign-up sheet by SRNML technicians. The SRNML reserves the right to preempt normal use for maintenance/repair, installations or special circumstances which cannot be successfully predicted and scheduled.
Limitations on scheduling: Qualified instrument operators may schedule in advance up to two two-hour blocks of time in a calendar week. However, once the operator has used up any part of the time that he/she has reserved, he/she may sign up for an additional amount of time equal to the amount already used during that week. Scheduling for each instrument will be done separately. Sign-up sheets will be posted at least one week in advance. If an operator needs to schedule time further in advance that one week, he/she should make arrangements with the SRNML Director or SRNML technicians.
Scheduling assistance from technical staff: If an SRNML technician is needed to conduct a researcher's microscopy, the researcher should contact the SRNML technician a week or two (the earlier the better) prior to needing the microscopy work. At that time, the SRNML technician can determine how much time will be needed to accomplish the microscopy. The SRNML technician will then block out these times on the scheduling list when it is posted. However, no more than ten hours of each week for all research needing an SRNML technician may be initially allocated on each microscope. If there are open blocks of time during the week, the SRNML technician should schedule what additional time is needed to accomplish his/her microscopy work for researchers.
No-shows: Anyone scheduled to use the SRNML facilities is expected to do so at the assigned time. If a person repeatedly does not use the microscope at an assigned time, privileges for use of the SRNML facilities will be restricted to open blocks of time during the week the microscopy is to be accomplished.
Costs for Using SRNML: All users must supply all disposable materials needed for their microscopy work. These include embedding materials and all materials involved in the photographic aspects of the user's microscopy work. Among the photographic costs are film, developer, paper, and fixer. A list of those items available though the SRNML can be obtained from the SRNML Director.
Hourly charges: Hourly charges for internal users will be calculated for all pieces of equipment having significant maintenance costs. These costs will be calculated by taking predicted maintenance costs and dividing by the expected hours of usage during a given fiscal year. The cost basis may include: (1) supplies required to maintain the instrument; (2) to service contract costs; (3) a prediction of user-billable charges that may be retained as a contingency fund; (4) inflation. The usership basis may take into account: (1) current usership trends; (2) courses to be offered; (3) past usership trends; (4) university contributions. Charges may be corrected quarterly as needed, but may not be increased in any fiscal year by more than 10%. Non-payment of charges may result in loss of privileges in the SRNML until payment is made at the discretion of the Director. Surcharges may be added for specific costly instrument configurations, such as LaB6 electron sources. [Approved SRNML Adv. Bd. 1-29-90]
External usage: External usage of the SRNML is restricted to academic and non-academic projects requiring microscopic services for the purpose of conducting original research. Such EM usage will be conducted by University of Oklahoma researchers on a contract or grant administered by the Grants and Contracts office. Prices for external usage will be based on all costs incurred by the SRNML in the operation of the facility, including: (1) direct usage and specimen preparation costs; (2) maintenance costs; (3) amortization of research equipment and facilities; (4) operator salaries; (5) fringe benefits; (6) administrative costs; and (7) indirect costs. [Approved SRNML Adv. Bd. 2-20-90]
Darkroom Facilities: There are two darkrooms in the SRNML. One is associated with transmission electron microscopy for processing photographic materials used with the TEMS. The second darkroom, located in the NML Room 209, is intended for users to print and develop electron microscopy materials. No other printing or developing is permitted in this room. Sign up procedures will be similar to those used for the microscope.
Log Books: Log books are provided for each piece of equipment in the SRNML. Each time a piece of equipment is utilized an entry must be placed in the log book. Entries will vary, but will include the name of the user, nature of use, date, and time (starting and finishing) of use. It is essential that these logs be maintained to facilitate instrument maintenance and to determine amount of use each instrument receives.
