| 22 | Celeste Pidcott |
||
| 23 | Francois Drielsma |
||
| 24 | Chris Rogers |
||
| 25 | Tanaz Mohayai |
||
| 26 | Ryan Bayes |
||
| 27 | John Nugent |
||
| 28 | Scott Wilbur |
||
| 29 | |||
| 30 | Millipede offsets etc fixed |
||
| 31 | - please show residuals plots |
||
| 32 | - confirming internal alignment |
||
| 33 | - getting ready for tracker to tracker alignment for next time |
||
| 34 | |||
| 35 | Francois, tracker sign flip (Drielsma) |
||
| 36 | - xflip - reading out fibres the wrong way for all the planes |
||
| 37 | - v and w were swapped |
||
| 38 | - wrong ordering of the readout is at reconstruction level |
||
| 39 | - plane swap comes from the geometry |
||
| 40 | - still need to verify fix in MC |
||
| 41 | |||
| 42 | Tracker alignment to field (VB) |
||
| 43 | - VB promises for something today or tomorrow(ish) |
||
| 44 | |||
| 45 | Cut-based beam selection (Scott) |
||
| 46 | - Scott has some working code that will do a framework for cut-based beam selection |
||
| 47 | - Do we want to run it inside the MAUS loop or just get it running? |
||
| 48 | - Figure out mapping from D2 current to timing windows |
||
| 49 | - Notes that D2 currents are not necessarily related in the expected way to TOF012; will turn into powerpoint for next time |
||
| 50 | |||
| 51 | Cut-based beam selection (Tanaz) |
||
| 52 | * Noticed that discrepancy between TOF peaks between summer and October runs |
||
| 53 | |||
| 54 | Likelihood PID (Celeste) |
||
| 55 | * Run PID on 2015 user cycle |
||
| 56 | * Things look like they are working well |
||
| 57 | * Nothing quantitative yet |
||
| 58 | * Things look reasonable |
||
| 59 | * Only been done for KL and TOF; EMR not MCing and Ckov not in framework yet |
||
| 60 | * Not yet looking at consistency between U/S and D/S as there are not yet enough detectors in place |
||
| 61 | |||
| 62 | Detector alignment |
||
| 63 | * Nothing more |
||
| 64 | * Could improve by using different tracker stations |
||
| 65 | * Need to correct for tracker pitch |
||
| 66 | * Looking at fitting distribution centre rather than calculating naive mean/RMS |
