* Apologies: - 
69 2 Franchini, Paolo
70 1 Franchini, Paolo
* *TOF*: agreed on the outline of the contribution. 3-4 pages.
71 7 Franchini, Paolo
** Plots we would like to include:
72
*** Time Walk calibration
73
*** Slab DT resolution (few examples, with TW correction)
74
*** T0 correction (few examples, for the software description)
75
*** Slab DT offsee (2D plots for each TOF)
76
*** Slab DT resolution (2D plots for each TOF)
77
*** Overall Slab DT (for each TOF) or only one number (for each TOF)
78
*** Space points creation efficiency (include MC?)
79 5 Franchini, Paolo
** Include a MC study.

81 1 Franchini, Paolo
82
* *Ckov*: photoelectron vs momentum curves to be reproduced.
83
84
* *KL*: first draft in place. To be refined/rebalanced once we have the other contributions.
85
86 5 Franchini, Paolo
* *EMR*: include low level efficiency and PID to reject positrons. Francois to work in his contribution once he his done with his manuscript.
87 1 Franchini, Paolo
88
* *Tracker*: agreed on 5 pages
89
** 1 page hardware
90
** 2 pages low level recon
91
** 2 track selection/kalman, noise, efficiency and resolution
92
A lot of analysis material is ready (and easily adaptable from 7469) and needs to be put together. The noise analysis has never been formalised and may require few more time; Chris R. has done some studies for a past VC. Chris can send around some of these plots made for his paper.
93 8 Franchini, Paolo
Paul K. has provided some introduction text and Melissa is coordinating the writing.
94 11 Franchini, Paolo
** Overleaf: https://www.overleaf.com/15352478jfxzzqfbzyxt#/58152572/
95 1 Franchini, Paolo
96
* *PID*:
97 5 Franchini, Paolo
** Scott has updated the software framework.
98
** Use some of the plots produces in Chris R. analysis
99
100 13 Franchini, Paolo
* *Track matching*: Chris R. showed residual plots produced for the emittance note (that won't be included in the paper). Is worth having them in the system paper in order to show the performance of this tool. First contribution from Chris' analysis.

** GitHub: https://github.com/chrisrogers1234/MICE-systems-performance-paper
102 1 Franchini, Paolo
103 13 Franchini, Paolo
* *Detector alignment*: Paul K. reviewed Francois' note. Francois to reproduce the equivalent plots present in the note for the data. Agreed on 4-5 pages.
104 1 Franchini, Paolo
105
* *Magnets*: tracker field note in progress; some work to do on the systematics. FC is the missing piece.
106
107
* *Target model*: note in progress and comparison with the LM data to be started (Paul S. suggested using a 700 MeV proton beam). We have to understand what could end up in the paper.
108
109 16 Franchini, Paolo
* *Absorber model*: Ajit has some code in place and Craig Brown is working on some density systematic too. Agreed on the following studies in terms of energy loss:
110
** geometry of the windows
111
** temperature (density): different probes show different temperature.
112 1 Franchini, Paolo
113 13 Franchini, Paolo
* *Diffuser study*: work in progress. Most likely will be a separate paper.
114 2 Franchini, Paolo
115 1 Franchini, Paolo
* Define a common set of cuts (where needed) using the MAUS cut structure (that once is included in MAUS would require another iteration of the reconstruction).
116
* Some contributions might end up in a separate stand alone paper.
