- Classified Research
Deadlines For Requesting Beam Time
Refer to the appropriate deadlines for the submission of General User proposals and declaration of
beam time for PRTs and Contributing Users.
General User Account
All users should set up a $1,000 operating account to cover operating
expenses while at the NSLS, such as charges for use of trades, shops, and stockroom withdrawals. A telephone access
code, for use in placing off-site calls and faxes, is associated with each operating account. Operating accounts,
which are subject to BNL overhead, are established by the user's home institution via a purchase order.
