16.11 The cyclotron and BigRIPS condition are now restored and we have good beam

     Count rate at F11 plastic is ~8 cps

     At F8, they are focued on 41Al (D5 Brho = 7.5235 Tm)

     At F11, they are focused on 40Mg (D8 Brho = 6.3208 Tm)

     Presently around Run R9_19

     3mm Pb is on the exit window of the first MUSIC at F11

     All variable degraders were out (that is not what we intended to have...see next note below)

    

16.35 The variable degraders were not in the positions we thought.  Now we make it as follows:

     Variable degraders 1.0 mm W (+1 mm Al) and 0.3 mm W (+1 mm Al)

     R9_24 just began

 

18:00 Beam stopped for stripper foil change

          Moved Pb degrader downstream, from window of MUSIC1 detector to hole of polyethylene shield in front of BRIKEN.

 

18:12 Stopped AIDA DAQ at run R9_43 (Ge filling will start soon)
