NMR operations: 800, 900 & 1000 MHz (UHF) NMR systems
G1. Allocation of access. A total of 70% of the available time on the UHF NMR systems is allocated equitably to UK academic Users.
Wellcome Trust and UKRI -funded research groups are given priority for available time on these systems on a competitive basis, subject to approval of their “Application for Access” form. All external groups can also apply for access to the other NMR systems in the facility.
Local Users at the University of Birmingham are allocated 20% of the time on the UHF systems. The remaining 10% is for other Users that do not fall within the previous categories.
Requests for a particular time are made on an online scheduling calendar, for which access is given following acceptance of the user policies, as appropriate.
Requests for access will be accommodated with the goal of optimising spectrometer usage while taking into account the order in which such requests are received, with only one pending request per institution permitted.
A request for priority of allocation of an instrument whose allocation was lost due to down time in the last cycle will be honoured first.
Online booking of spectrometer time and the meeting room is available, as appropriate.
G2. Review of access. The NMR Staff and Management Committees will review the applications and schedules to ensure that fairness and equal opportunity for peer review and internationally competitive research are in place. The committees will resolve disputes as to scheduled availability, downtime, and other operational issues. Reserved but unused NMR spectrometer time will be charged as this prevents access by other Users.
G3. Trading slots. The exchange of slots during a quarterly schedule is entirely appropriate and only requires that the two parties agree, and that they inform the HWB•NMR staff. Exchange, or other trading of slots outside a current cycle, however, raises issues about the accounting of the slot, and about availability. Out-of-schedule swaps are then solely between the two parties, and the party designated in the current schedule has the full responsibility for use, for the accounted debit, and for any damage resulting from accidents or incidents.
G4. Downtime issues. The offer of the opportunity to use the instrument obviously requires that the instrument be operational. For addressing the issue of whether the instrument is operational, the instrument is required to pass the Standard Acceptance Tests for three channels of operation, and one probe must be operational for at least three channel performance. HWB-NMR staff keep the instruments in optimal working order and perform regular tests. However, breakdowns occurring in between regular testing cannot be excluded. If the user suspects malfunctioning of the instrument, it is their responsibility to perform the Standard Acceptance Tests for three channels of operation. Credit for downtime will accrue only on receipt of this information. Staff will attempt to remedy downtime conditions as far and as soon as possible. The following conditions clearly result in downtime, and require no testing.
- Magnet failure
- Failure of computer controller to boot
The following conditions, on their own, will not be considered to result in downtime:
- Failure of one probe when another is functional
- Lack of disk space on a computer when data transfer would permit adequate space
- Any sample related problem
Redress of downtime. The member institution’s request for earliest priority of use for the previously down instrument in the next schedule will be met, to the greatest practical degree. In the case of multiple member institutions with downtime requests, they will be prioritised by length of total downtime.
G5. Appeals and disputes. Users should discuss any difficulties with the staff as soon as practical. In cases where the allocations of time, of staff resources, or other questions arise, when discussion with the staff has taken place and when Users are still in dispute, Users may address the Director who may invite a written appeal. The Director will, within the next 10 working days, make a recommendation to the Operations Manager for any redress or change of procedure. In the case of accidents or incidents, a separate procedure will involve the Health and Safety Committee.
G6. Accounting. Accounts of actual use time will be maintained by recording login sessions.
G7. User and staff responsibilities.
a) On Tuesdays, spectrometers will generally not be available between 9am and 2pm to allow for weekly cryogen filling and routine service. This period may be changed if necessary, to facilitate up-keep of the magnets. In addition, Users must permit staff to change probes and to operate the cycling of the cryoprobes for their continuing operation and performance.
b) Users will generally operate with standard operating protocols and methods, and are not permitted to modify the NMR hardware, software or implement new pulse sequences without explicit permission from the NMR staff. Users are required to consult with NMR staff for
- any unusual use of high power amplifiers including extreme power levels or pulse lengths
- any other expected condition which may imperil the instrumentation, including extreme temperatures
Users must leave the operating programs in the standard condition. If users write or modify a pulse program, these versions must be clearly named to distinguish them from the standard condition.
c) Users will submit ’application for access’ and ‘user agreement’ forms as required to gain access to the NMR systems.
d) Users will assist the staff in the cleaning rota and with magnet filling, and will endeavour to keep the facility including kitchen, sample preparation lab, and NMR chambers cleaner than when they entered.
e) Staff will prioritise the removal of previous Users’ data so as to permit maximum use to the current Users.
f) Staff priorities will be human safety, instrument safety, attempted resolution of downtime issues, attempted resolution of other performance issues, and training and other operations.
g) Users should finish their experiments by 12 noon on the 800, 900 and 1000 MHz spectrometers unless they are also using the instrument overnight. Users of the other NMR systems should finish their experiments by 3pm to accommodate Users who may be taking the overnight slot. This arrangement may be varied by mutual agreement of the relevant parties.
h) Users who prevent other Users from using overnight slots by over-running experiments beyond 12 or 3pm (see point g) will be charged for overnight and over weekend usage.
i) Users who book time online but don’t use it will be charged for the time since they are preventing use by other Users.
NMR operations: 500 & 600 MHz NMR systems
Same as above except that:
- users are typically from the University of Birmingham, and other Universities, Hospitals or Institutes in the neighbouring region are given priority access, although other groups inside or outside the UK are welcome to apply for access to any available time.
- the user fees are unique to each system configuration including magnet, probe and autosampler.
- subsidies may be made available to new or underfunded Users upon request, to collect preliminary NMR data for grant applications, for example.
Access to the spectrometers for internationally competitive scientific research is intended to be fair and equitable. Access fees will be charged on the basis of login time to a given NMR system, or on a per sample basis. Users will be billed monthly. Rates will be reviewed annually and will differ depending on the user affiliation (i.e. commercial, academic, internal).
