Current Status

• We are running with 3He in setting 2 (first cycle), page 160 of the runplan. We have completed 65K/72/K good electrons according to the online analysis.
• We ran with 40 uA until 3 am this morning and then we were lowered to 30 uA ever since. Probably, we will continue running with this current unless the beam trips increase and we have to be lower again.

Current Run Plan
