FEI tecnai t12 POLICIES AND PROCEDURES
Billing schedule:
Charges are invoiced at the end of each calendar month. Internal charges are directly uploaded to Banner.
Supervisors should review charges in FOM each month to limit the need for manual adjustments after charges have been uploaded. Users may contact the facility director to discuss any disputed charges.
Rates are published on the website and calculated in consultation with the Controller’s office.
There is a minimum charge of 15 minutes of use.
Reservations:
Reservations are made in half-hour time increments.
In order to promote additional usage while still providing less frequent users adequate access, daytime weekday reservations (8 AM – 5 PM) are limited in total hours per user per instrument at any given time. For the Tecnai this is set at 8 hours.
There is no limit on the number of hours reserved overnight and on weekends.
The schedule is open for reservation 14 days in advance. If special circumstances require reserving a time further in advance, contact the instrument manager.
A user can immediately access an unreserved instrument during the day (via express logon) regardless of other reservation limitations.
Daytime, Evening and Weekends:
In order to promote additional usage while still providing less frequent users adequate access, weekday daytime reservations (8 AM – 5 PM) are limited in total hours per user per instrument at any given time. For most instruments this is set at 8 hours.
There is no limit on the number of hours reserved overnight and on weekends.
There are currently no billing distinctions between day and evening use, however, in order to encourage the development of proficient users and not limit productive research, usage over 12 hours/month by one user on one project is charged at 30% of the hourly rate for this instrument.
Flexible start/end time:
Start/end time is calculated to the second so that you are billed for the actual instrument time you have used.
Unused reservation:
If user does not show up within 30 minutes after reserved start time, the reservation will be cancelled and another user may use the time period. The user who made the reservation will be charged a half hour no-show/late cancellation fee.
Cancelled reservation:
Users will not be charged if a reservation is cancelled more than 24 hours before the reserved time begins. Users will be charged the equivalent of a half hour of usage if the reservation is cancelled less than 24 hours in advance because this limits the ability of others to make use of available instrument time. If there are extenuating circumstances, such as a medical emergency, the late cancellation fee will be waived.
If an instrument is down, users will not be charged for unused reservations and do not need to cancel their reservations.
Forgetting to login/logout:
Users should notify the instrument manager or leave a note in the FOM comments if they forgot to log in to FOM at the start of their session or forgot to log off FOM at the end of their session.
Report of equipment problem:
If an instrument is not functioning properly during the session, the user should notify the instrument manager as soon as possible. This can be done in person or in the comments in FOM. For reports in FOM, instrument managers will receive an email notice and address the problem as soon as possible. Instrument managers will also determine whether the usage charge should be reduced or waived due to the problem reported.
