For the most part, there will be no project prioritisation. The timeslot on the instruments will be attributed on a first-come first served basis, following the booking and cancellation policy. In case an instrument becomes heavily used, priority will be given to internal academic projects. Time-slot restrictions might be applied to each project depending on the nature and requirements of the individual projects. Restrictions and prioritisation will be decided, on a case by case, by the technicians.

1. Reservations will be accepted between (8:30am-3:30pm) on weekdays.
2. No reservations will be accepted after hours (3:30pm-10:00pm), during weekends or on holidays.
3. Under no condition may the equipment or the data acquired be used for personal goals or any objective other than the ones related to the approved scientific project.
4. Under no condition may the equipment or the acquired data be used in malicious or misleading ways, intentionally or not.
5. Users should always clean their workspace and leave the instrument in the condition they would like to find it.
6. All users must go through the proper training given by the technicians before taking the LI-6800.

10. Once the reservation is over, the LI-COR 6800 has to be returned to the Research Greenhouse. Users will be shown where to place the instruments if returned after hours (3:30pm-10:00pm)
11. The LI-6800 must be returned every day unless special permission is given by technicians.
12. Users should refrain from bringing the LI-COR 6800 out in the field when it is raining or bad weather conditions are expected.

A bill will be sent to your corresponding PI at the end of each month by the Core system (ECP3).

The amount that is billed will depend on the amount of days the LI-COR 6800 is reserved for. The minimum reservation limit for the LI-COR 6800 is one day. Users will be charged for the day even if the instrument is not used for the entire time.
