Jin,

Look at the bottom of the EMCAL SiPM's tab here:

https://docdb.sphenix.bnl.gov/0000/000034/001/T1044-2017a-2.xlsx

Sean and I spot checked a number of these towers at BNL. There could be mistakes, but cosmics look reasonable.

Hi, Martin and all

Thanks! This flag is very convenient. This switch is incorporated into a
not-yet-merged prototype3 production code:
https://github.com/blackcathj/coresoftware/commit/3236ced2bc2c604a94ab94cd8f3fa9a1daa9259a

Now I will also appreciate if someone could point to me the new HBD channel
map for high-eta EMCal, which will put here:
https://github.com/blackcathj/coresoftware/commit/3236ced2bc2c604a94ab94cd8f3fa9a1daa9259a#diff-4943c7156628a48058c793384d2269b3

All, especially Jin,

I started to summarize the current PRDF structure changes as compared to
2017.

I added a chapter "What is new in the data structures in 2017" in
https://wiki.bnl.gov/sPHENIX/index.php/2017_calorimeter_beam_test#What
_is_new_in_the_data_structures_in_2017

Basically we are reading more scalers in packet 910/911, and added one
camera packet 944 (not to let a cam go to waste).

begin-run packet 905 (just its presence, not content) indicates that the new
(high-eta) emcal is connected. Example code on the Wiki.

Best,
Martin

Hi, John and Martin



Thanks for the lots of work initiating the test. 8-GeV scan sounds
like a good plan. And I think Martin's marker packet in PRDF will be
very useful for analysis too (good to have a copy in numerical format too).



I didn't understand the suggestion in the PbGl item in the

wiki to "make sure timing peak of the lead glass data is stable with
in one

BCO."



Hmm. I guess I should say move the PbGL signal earlier in the sample
train. In the past run 2016, the PbGL was recorded with peak around
sample 15-21. Almost for all events, the tail of ADC spectrum just
fall off the cliff beyond max sample of 24. Although one can still fit
for the max, this prevented us to perform an analysis of 1100V to
1200V comparison by just integrate the ADC count (although signal
shape could change between two HV settings, presumably the ADC
integral remain the same.). Example 2016 data shown below.



Therefore, the request I meant is to move the PbGL trigger to come
100-150ns later, so we could sample the whole curve. Wiki updated.





To make this data widely useful, we'll need to run the production and
look at

it--that can be done remotely if we update the wiki with runs that we
deem

worth analyzing.



A wiki run list will be useful. Just chat with Chris, that we will
setup a new code base for prototype-3 analysis and decouple it with
prototype-2. A channel map will be useful in setting up the PRDF
unpacker. Most other infrastructure should be similar. When production
is setup, I also need to work on the analysis tutorial ...



Cheers



Jin

Jin and Abhisek,



Thanks for putting this together, after last week's beamline scare I
thought

maybe we better have a plan that would get us some of what we want in

short order in case the septa failed completely.



Looking over the list and thinking what we need to get done this
weekend to

confirm that we have everything connected and working to the best of
our

knowledge, I think we should spend most of our time this weekend at

-8 GeV and take data at



- sweet spot of EMCAL3

- PbGl

- HCAL only

- sweet spot of EMCAL2



in that order, which will debug/verify the hodoscope, the Cerenkov
counters,

our own detectors, and give us some experience with the wire chamber
data,

and would let us exercise new analysis necessary for the

EMCAL3 (the channel map is new). It seems to me that ideally, we
could

then produce, albeit with unit calibration constants, resolutions for
the two

EMCAL's and the HCAL alone which could be directly compared with last
year.



In looking at what we've installed and done, I think it would better
than

trying to start with a big calibration scan, before we have fully
established

that everything is works and we can analyze it as we did at the end
of
the last

beam test, and we'll be lucky to get through this in a weekend.
Also, it

doesn't require a lot of beam development, and since the beam has
been off

for so long, there may be startup hiccups when we ask for changed

conditions. -8 GeV seems like a good way to start for that reason,
and

because we have a lot of data from last time there. If we take this,
have time

to study it, and are ready to go on, I think the next thing would be
an energy

scan in the PbGl. I didn't understand the suggestion in the PbGl
item
in the

wiki to "make sure timing peak of the lead glass data is stable with
in one

BCO." As far as I know, there is no way to synchronize the ADC clock
with

beam events, and I hope that nothing we did in the past relied on the
peak

being in any particular sample.



Also, we will be sharing time for the next few days with T-1068,
which I

believe is development of an SVX4-based Si telescope by groups from
KEK

and Osaka for tests of ATLAS pixel and strip detectors, I would guess
they'll

want 120 GeV protons, and if we wanted to run parasitically with them
(not

sure we have the person-power to do that), we could in principle take
MIP

calibration data with them in the beam, they should be pretty low mass.



To make this data widely useful, we'll need to run the production and
look at

it--that can be done remotely if we update the wiki with runs that we
deem

worth analysing. We'll have to exercise some care in changing
EMCAL's,

since the geometry and channel map are different, but the data will
look

exactly the same unless we do something to identify it. We could
change the

packet id, I suppose, but that would take the HCAL and hodoscope with it.

Also, we have to make some changes to the database to account for two

emcal's and changes to the hcal controller.

Hi Don,



Thanks for the update! I certainly appreciate that you want to

keep the engineering meeting tight, but I'll look forward to poking

through the slides.

Hi John,







We won't have any Engineering input for tomorrow's meeting, as
we

are meeting with Walt Sondheim on MAPS parameters at the same
time.

We do have a BNL internal Calorimeter engineering meeting on
Friday

to go over Anatoli's latest analyses, Rich's current light

collection design status and general engineering issues for

finalizing HCal mechanical design (steel, light collection,
etc.,

inner and outer) and advancing the EMCal mechanical design.







We are not putting this on bluejeans, as we want to keep the

engineering discussion tight, but we will post some slides on
Indico.

Dear HCAL'ers:



It's been a while, but we will resume our bi-weekly HCAL

meetings this coming Wednesday, Jan 18th, at 2:30PM BNL time. The

agenda is evolving here at:



https://indico.bnl.gov/conferenceDisplay.py?confId=2762



I'm hoping we can get an update on the test beam, and maybe
some

additional contributions.



Regards,

John
