The solution was to drop back to version 2.0.1.

This behavior was seen on CentOS 7 (as is run on ifarm) when building non-CPP specific version sets. In particular the problem is there with version_5.2.2.xml, but not with version_5.2.1.xml. So the error is still out there. Recall that neither 5.2.1 nor 5.2.2 have been built at JLab.

CPP/NPP Run 6/8-7/27/2022

CPP Meeting, April 28, 2021

• Rory presents note on construction. tries for comprehensive document, a gluex doc by the afternoon
  • electronics, schematics, parts choices, Humiseal
  • grounding scheme
  • assembly and construction
  • testing procedure
  • testing results, drift time relationship measurements with different gasses
  • operation
  • appendix with mechanical drawings
• Rory: get eighth detector going
  • first window for coming down: week of collab. meeting
  • solo trip initially, drop off chambers
  • send Albert later (first visit to JLab for him)
• Elton: updated ERR response document
  • cleanup done
  • incorporate ? from Ilya
  • timeline for publication
• Elton: schedule review
  • now stuff: mechanical ordered,
  • Hai finished stuff on test stand for trigger
  • microscope: confirm high end of microscope decided, distance from window, GlueX 9 mm fro focal plane, but on focal plane for 6 GeV, does not effect maufactured pieces, still set
  • software: middle of geometry (Beni) and reconstrcution underway (simon)
• Elton: publication schedule
  • Rory: time-scale driven by simulation, what we have is reasonable
• Elton: responsibilities
• Simon: pushed tracking changes to github
  • made geometry change in HDDS repository, not in CCDB yet
  • Beni will do that
• Elton tried muons with mcwrapper, crashed early on
• Beni: test area prep
  • EEL 126: contact made with Walt Akers and Jack Segal
  • want chambers horizontal to use scintillators as trigger
  • 90/10 by volume at STP, 5 cc/s
  • Rory will bring HV power supply
  • Need low-voltage power supply at/from JLab
• Elton: need a meeting on electronics with Fernando, Chris, Hovanes
  • use next week Wed. 9 am slot
• Beni: get Tim’s crew involved in physical moving of stuff
• Andrew:
  • FCAL elasticity
  • difference between kinfit energy and measured, as a fucntion of energy
  • do a fit for an empirical correction
  • elasticity looks much better
  • at beamline meeting eugene questions a 0.04% pion contamination

Running b1pi_test with CPP Geometry

Here is a set-up file:

. /data/gluex/Linux_CentOS7-x86_64-gcc4.8.5-cntr/gluex_top/gluex_env_boot.sh
gxenv
export JANA_CALIB_CONTEXT="variation=mc_cpp"   
export JANA_GEOMETRY_URL="ccdb:///GEOMETRY/cpp_HDDS.xml"

Here is the command that was run inside a CentOS 7 Singularity container:

/home/marki/git/hd_utilities/b1pi_test/b1pi_test.sh  -d /home/marki/git/hd_utilities/b1pi_test -4 -r 30300 >& bp0.txt &

Muon Chambers and Geant4 Meeting, February 22, 2021

• Present: Ilya, David L., MMI
• Code for CPPSim in subversion, under trunk/Experiments
• Geometry in CPPSim: HDDS -> ROOT -> GDML -> Geant4
• Hits in halld_recon
  • already in event.xml
  • place to hold energy in cells
  • under forwardMWPC
• mcsmear knows about FMWPC
  • FMWPCSmearer
  • threshold for energy set to zero
• halld_recon library: FMWPC
  • truth info could be enhanced
• HDDS: ForwardMWPC.xml
  • geometry not defined at cell level
• HDGeant4
  • Richard put in code to generate hits
  • testing needed
• HDDS top-level geometry
  • cppHDDS.xml
  • contains CPP target
  • top-level should be an option to specify where relevant
  • cppDIRC-HDDS also exists for the test set-up, implemeted by Elton
• MCwrapper hook for CPP exists
  • need to ask Thomas about which simulation program is run, HDGeant4 or CPPSim
• Placing event at the CPP target position
  • CPPgen2pi used genr8 format, converted with genr8tohddm
  • vertex can be specified in genr8tohddm
• Reconstruction code
  • nothing done beyond counting hits so far
  • e.g., matching hits to tracks not done

CPP Meeting

• David, Elton, MMI; Andrew, Rory
• Andrew shows FDC pseudo hit distribution in x-y plane

CPP Meeting, October 30, 2019

• present: Rory, Andrew, Elton, Ilya, David, MMI
• Andrew, simulation
• Ilya, shielding
• Rory, chambers

CPP/NPP Talk Preparation

Outline

• Theoretical introduction charged and neutral
• charged experimental situation
• plans at Jlab for charged
  • gluex detector
  • modifications to the gluex detector
  • analysis tricks
• plans for neutral
  • experimental situation
  • contrast with charged
  • rate expectations
  • expected sensitivity

Notes

• there was a sesaps 2018, in Knoxville. http://www.phys.utk.edu/SESAPS18/ . It was Nov. 8-10
• David’s talk has a date of Nov. 17, 2017
• SESAPS was in Milledgeville, GA from Nov. 16-18, 2017. Host by Georgia College and State University
• Chiral Dynamics 2018, was Sep. 17-21, Durham, NC. https://www.cd18.org/ .
  • David’s talk: https://docs.google.com/presentation/d/1ClMYHfVCBW4qkFO_HZVRqrasb6QS9l6dxvJXkKeO1oE/edit?usp=sharing
• Angular distributions:
  • Phi plot: azimuthal distribution pi-pi system (viewed as a single particle) in the lab frame vs. polarization plane (also in lab frame). Note that pipi-system direction in lab will be opposite proton direction in lab
  • Psi plot: azimulthal distribution of pi+ in helicity frame (rho rest frame) with respect to production plane (in rho rest frame). production plane is defined by incoming photon and outgoing proton in this frame.\
• This SESAPS has a web page: https://uncw.edu/phy/sesaps2019/index.html
• Talk is at https://docs.google.com/presentation/d/1EjRJQMaZgzbIuv5vSekngkJNAxrqWqqa3BtCOlYF5II/edit?usp=sharing

Comments from Practice Talk

• Jose: mention proton polarizability
  • experimentally accessible
  • value tiny, hadrons very stiff
  • contrast with atomic polarizabilities
• add slide numbers
• there is data at low m pi0 pi0, plot does not reflect it, do not emphasize
• spread out the lines on interplay of theory approaches
• point out left side is experimental landscape, right side is theoretical landscape
• gamma gamma to single pi0 both polarization and normalization
• gluex detector needs BCAL label
• experimental conditions, lose the yellow highlight and just remake slide
• muon chambers have iron absorbers, lead shield in front
• angular distribuiton plot, pure rho is flat in one, pure primakoff is flat in the other
• primex 1.5% accuracy only if CPP has equivalent statistics, look up Ilya’s statement in LOI
• CPP sensitivity plot: 5.7 is the chiPT value
• NPP past: use one plot, sqrt(s), explain it
• add Dai and Pennington reference
• 0.8 in neutral pi plot comes from XTal ball using |cos theta|< 0.8
• [Serpukov result 2 decades old]
