Getting started

People who can reserve instruments:

  • someone listed as a PI in CORES
  • a lab manager or assistant who can act as a PI in CORES
  • a person who has been made a user in CORES.


If you want to be an instrument user, ask either the service core manager or your Principal Investigator to make you a user. However, the person in charge of the grant you use has to give you access to a PTAO for billing, as described elsewhere.

A Principal Investigator can make someone a user in CORES by logging on to CORES and selecting Reservation Module User Maintenance to add a user, and choosing a PTAO to use for that instrument.

To reserve some instruments, you need to be approved by the core manager.
