User Flowchart

All users of CAAAM facilities are required to maintain current safety training certification specific to the hazards contained within CAAAM. The appropriate training courses are linked below, and are valid for 1 year after date of completion. All users must send verification of completion to the lab manager.

Accessing CAAAM Facilities

CAAAM Facilities are booked and charged through the FOM System. For internal users, a current FOM user account is required. To create an FOM account, the Account Information Form must be completed, signed, and sent to the lab manager. Users with an existing FOM account must send their previously completed Account Information Form to the lab manager. Once an FOM account is active, users will book time on FOM, and will be charged for equipment hourly usage per the CAAAM User Fee Schedule.

Users should request training (Training Request Form) for specific pieces of equipment if they intend to perform continuous work in CAAAM. Untrained users, especially for undergraduate projects or one-time depositions, will have to work with the lab staff for planning and operation of equipment.

To start any project with CAAAM facilities, a user must complete an outline of their project on the Initial Proposal Form, and bring a printed copy of that form for short review by the lab staff during weekly office hours, Fridays 12 p.m.–5 p.m.

All external users will communicate with the Center Director and lab manager for their specific needs.
