Safety Documentation

Users are required to have Jefferson Lab safety training, including EH&S and radiation worker training, which are regularly scheduled, and ODH training / testing, which is given by the User Liaison Office.

Please read, understand and sign these documents:

COO: Conduct of Operations for E05-004 and E05-103
ESAD: Experimental Safety Assessment Document for E05-004 and E05-103
RSAD: Radiological Safety Analysis Document

A copy of the Hall A 2002 RWP is in the counting house. Please read and sign it if you have not already done so.

Targets Installed for LEDEX (Meekins summary)
Sieve
Previous Hall A experiments have used a radiator mounted immediately upstream of the vacuum chamber or a radiator installed directly in the cryotarget cell block. The photo-disintegration experiment needs a radiator close to the target due to low beam energy, but far from the target due to small lab angles being measured. The new radiator is documented here.

HOW-TO: Updated shift worker procedures for 2006 LEDEX experiments
- Update to the updated Procedures for checking the Raster/Beam-Spot
- Important instructions for setting momentum below 500 MeV/c
Guide to Hall A shift worker procedures
(note: this is taken directly from E00-007, so a lot is very useful, but some is out of date)
