General Guidelines:

  • Instrumentation facilities are available for a limited number of external users for nominal fees which are accumulated to sustain MAC operation and instrumentation maintenance.
  • For individual use, users have to schedule instrumentation in advance through our online scheduling system: http://faces.ccrc.uga.edu/The group name is SEMA, and the individual username and password is provided by the MAC manager.
  • External user access to MAC facilities is limited to weekdays from 9AM to 5PM.
  • All new users will be trained with an instrumentation expert from SEMA lab.
  • A separate password-protected account will be assigned for users to log into the systems.
  • Users (faculty members and companies) will be billed every quarter:
    • March 31
    • June 30
    • September 30
    • December 31

User fees on major instruments (external user fees are available per request):

  • Measurements conducted by MAC members:            $70/hr
  • Training sessions:                                                         $60/hr
  • Independent measurements of approved user:           $30/hr
    (discounted for other instruments, see list)

How to get started:

  1. Contact MAC Director (Dasha, bukharinad@gatech.edu) on availability of instrumentation and general guidelines (limited number of users can be assigned during one period).  MAC Internal GT User Form
  2. Provide account number arrange for training, manuals, and SOPs on the new user form.
  3. Get trained and start using instrumentation, provide all consumable (e.g., AFM tips).

MAC FACILITIES
