Prototype-Prototype LunDMX Meeting 17 June 2020 Ruth Pttgen What it should look like (minus the first layer) absorber 25mm x 697mm x 697mm 20mm scintillator, 2m long, 8x50mm in the front, 12x50mm in the back 2mm air gap around absorber


  1. Prototype-Prototype LunDMX Meeting 17 June 2020 Ruth Pöttgen

  2. What it should look like (minus the first layer) absorber 25mm x 697mm x 697mm 20mm scintillator, 2m long, 8x50mm in the front, 12x50mm in the back 2mm air gap around absorber —> put this into a gdml file, following hcal.gdml L DM X LDMX HCal 17 June 2020 � 2

  3. What we currently have side view exploded view Note: bars not put in geometry individually! L DM X LDMX HCal 17 June 2020 � 3

  4. First Simulation Using v1.5 of ldmx-sw 500 MeV electrons fired from z=-1m 500 events also ran reco, but that will need more work… L DM X LDMX HCal 17 June 2020 � 4

  5. Sim Hits — x, y L DM X LDMX HCal 17 June 2020 � 5

  6. Sim Hits — z should do generate a few more events, but looks like there are 19 layers L DM X LDMX HCal 17 June 2020 � 6

  7. Sim Hits — Energy L DM X LDMX HCal 17 June 2020 � 7

  8. Reco Hits mostly noise L DM X LDMX HCal 17 June 2020 � 8

  9. Reco Hits not sure what is happening here L DM X LDMX HCal 17 June 2020 � 9

  10. Reco Hits removing noise hits — still weird L DM X LDMX HCal 17 June 2020 � 10

  11. Reco Hits x-y position of non-noise hits L DM X LDMX HCal 17 June 2020 � 11

  12. Sim Hits x-y position of hits L DM X LDMX HCal 17 June 2020 � 12
