Pion-LT/Kaon-Lt Meeting: Wednesday, October 26, 2022
|
|

|
Normally, pion-LT would go first today, but Richard had to leave early for
|
|
4
|
travel to DNP, so he went first.

Richard:
|
|
9
|
At the quarterly analysis meeting, Peter Bosted mentioned the luminosity
|
|
10
|
scan runs that had been taken just after Kaon-LT. These were taken with only
|
|
11
|
one arm at a time (both set for electrons I think), so should be easier to
|
|
12
|
interpret. Richard is looking into those runs.
|
|
13
|
|
|
14
|
Peter also provided information about some the rate-dependent effects he
|
|
15
|
observed/found corrections for [DG note: some corrections may depend on the
|
|
16
|
version of hcana used, as well as exact value of timing cuts I think]
|
|
17
|
|
|
18
|
Also working on using Bill's cross section code. Need an example of Bill's
|
|
19
|
root trees to understand structure.
|

|

21
|
[There was some discussion about what Bill's code does since DG is not
|
|
22
|
familiar with it. Perhaps would be useful to have Bill attend a meeting to
|
|
23
|
give a brief overview?]

Jacob:
|
|
26
|
Not much to report (was traveling). Trying to meet with Holly to discuss
|
|
27
|
HMS and SHMS optics (see discussion from a couple weeks ago).
|
|

Nathan:
|
|
30
|
Busy with committee reports and coursework - no analysis updates this week.
|
|
31
|
|
|
32
|
Junaid:
|
|
33
|
Also busy with committee report (2nd draft).
|
|
34
|
|
|
35
|
Jacob expressed interest in seeing committee reports. Nathan and Junaid
|
|
36
|
agreed to pass them along when finalized. [DG comment: provides good example
|
|
37
|
of style of discussion appropriate for thesis].

Ali:
|
|
40
|
Working on implementing the spectrometer/angle offsets that Peter came up
|
|
41
|
with when analyzing all the SIDIS/Kaon-LT data and seeing how well they
|
|
42
|
work with the Heep data. Peter basically only has an offset for the HMS central
|
|
43
|
momentum (this offset is a function the HMS momentum).
|
|
44
|
|
|
45
|
[DG comment: I think Peter also includes on offset for the HMS out-of-plane
|
|
46
|
angle. This has been around since the 6 GeV days, so might already be baked into
|
|
47
|
replay offsets.]
|
|
48
|
|
|
49
|
Also taking another look at tracking parameters and tracking efficiency
|
|
50
|
determination.

Meeting next Wednesday at the same time, then the following week

|
53
|
switches to the new meeting time: 7:15 Regina/8:15 Eastern
