<p>16.11 The cyclotron and BigRIPS condition are now restored and we have good beam</p>
<p> Count rate at F11 plastic is ~8 cps</p>
<p> At F8, they are focued on 41Al (D5 Brho = 7.5235 Tm)</p>
<p> At F11, they are focused on 40Mg (D8 Brho = 6.3208 Tm)</p>
<p> Presently around Run R9_19</p>
<p> 3mm Pb is on the exit window of the first MUSIC at F11</p>
<p> All variable degraders were out (that is not what we intended to have...see next note below)</p>
<p> </p>
<p>16.35 The variable degraders were not in the positions we thought. Now we make it as follows:</p>
<p> Variable degraders 1.0 mm W (+1 mm Al) and 0.3 mm W (+1 mm Al)</p>
<p> R9_24 just began</p>
<p> </p>
<p>18:00 Beam stopped for stripper foil change</p>
<p> Moved Pb degrader downstream, from window of MUSIC1 detector to hole of polyethylene shield in front of BRIKEN.</p>
<p> </p>
<p>18:12 Stopped AIDA DAQ at run R9_43 (Ge filling will start soon)</p>
