Unless otherwise specified, beamtime starts at 9am on the initial date and ends at 8am on the final date.

Important -- Cryogenic Users: The NSLS will provide liquid helium for the far infrared detectors only. Unless otherwise indicated, we will assume 1 detector operating each day of beamtime. Users with other cryogenic systems (e.g., ones brought to the NSLS or made available by an on-site research team member) must provide the required liquid helium. You will need your BNL 81XXXX account to place the order at 631-344-2964. Orders must be placed before 10AM on the workday prior to delivery, which occur on Mondays, Wednesdays and Fridays, excluding holidays.
