1. Run16
Y. Akiba

2. RUN16 The last data-taking run of PHENIX 20 cryo weeks
10 weeks of
5 weeks of d+Au energy scan
Starts the cooling-down on 1/19

4. RUN16: 10 week of GeV
Complete the Heavy Flavor measurement with VTX/FVTX
Approximately double the data set of RUN14
VTX was damaged by the beam accident in RUN15; It is now repaired and is ready to take data
Trigger strategy?
Luminosity profile? We may want to have flatter luminosity for a long time. At the beginning of a fill, the collision rate in the narrow vertex exceeds our DAQ bandwith (~7kHz)

5. RUN16: dAu Beam Energy Scan
PRL114
RUN14 3He+Au
PRL115
RUN15 p+Au
QM2015
Complete the study of QGP in small systems
Investigate the Onset of perfect fluidity
We requested 7 weeks of dAu for 4 energy points (200,62,39,20) in the BUP
PAC recommended 5 to 7 weeks
20 week of RUN16  5 weeks for dAu Beam Energy Scan

6. RUN16: dAu Beam Energy Scan
Reduction to
5 weeks
of data taking
Thanks to the increase of the luminosity at low E, we can do all of 4 energy point in 5 weeks
Efficiency at PHENIX side is required
Denis presented our case in the Machine/Exp meeting

7. PHENIX status Time meeting
Calendar
Denis’s slides in Time Meeting
on 1/26
Watch shifts started 12 January
subsystems initial setting up done, but still optimizing.
Magnet ramped on, is OK, will stay off during AuAu setting up as requested
UPS 15KV temporarily connected
DAQ running will all subsystems in
Full shifts started 26 January
First (physics) collisions in PHENIX expected by Feb
Ready for stable Beam KHz collisions for timing BBC ZDC and then all other subsystems
Accesses can be welcome. Still optimizing.
