sPHENIX HCal discussion

["Huang, Jin" <jhuang AT bnl.gov>]

Hi, John

 

Thank you for the update! Couldn't wait to be back again next week.

 

Meanwhile, would someone at the counting house volunteer to update the good run list to wiki?

·       We have one page for EMCal data followed by analysis notes: https://wiki.bnl.gov/sPHENIX/index.php/T-1044/EMCal_good_run_note

·       And the joint data page is still empty: https://wiki.bnl.gov/sPHENIX/index.php?title=T-1044/join_data_good_run_note  

·       Also a summary page that links to both: https://wiki.bnl.gov/sPHENIX/index.php/T-1044

Even copy paste from the Excel file between <pre>...</pre> tags works too.

 

Cheers

 

Jin

> The move took longer than I expected, because we had to do a substantial

> amount of rearrangement of cables, and we took our time to do it carefully

> and had our ORC re-review on Tuesday morning.  We passed that with no

> problems, and resumed operation with the beam Tuesday morning.

> We checked that things look pretty much the same downstream as they did

> upstream, so we decided to take the first slug of energy scan data of all three

> calorimeters in their final configuration.  Abhisek and the whole crew here

> took energy scan data last night from 12 to 40 GeV so if we're hit by a meteor

> we have data with the whole detector.

> So the things on my list of things to do are:

>

> - do a nose-down calibration of the emcal in this position (this will be

> somewhat more laborious, since it will require 8 accesses, but I think we

> should confirm that the EMCAL is stable (I'll need guidance from Sean and

> Craig to do this)

>

> - take HCAL data with EMCAL out of the way

>

> - do a first pass on the tilemapper (that's going on now)

>

> - we'll want to do another EMCAL energy scan, presumably after the

> calibration run

>

> After we've seen some analysis results from these data, we will probably

> have to decide how to iterate this.

>

> In general, we're in good shape--we have the early data we wanted to get,

> and we have two weeks to complete iterations on the data taking and

> analysis.

>

> If you have suggestions, please post to the list.
