* *TOF*: agreed on the outline of the contribution. 3-4 pages.
71 1 Franchini, Paolo
72 29 Franchini, Paolo
* *Ckov*: photoelectron vs momentum curves to be reproduced.
73 28 Franchini, Paolo
74 29 Franchini, Paolo
* *KL*: first draft in place. To be refined/rebalanced once we have the other contributions.
75 1 Franchini, Paolo
76 29 Franchini, Paolo
* *EMR*: include low level efficiency and PID to reject positrons.
77 1 Franchini, Paolo
78 29 Franchini, Paolo
* *Tracker*: agreed on 5 pages
79 1 Franchini, Paolo
** 1 page hardware
80
** 2 pages low level recon
81
** 2 track selection/kalman, noise, efficiency and resolution

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.
83 1 Franchini, Paolo
84 29 Franchini, Paolo
* *PID*: Scott has updated the software framework.
85 1 Franchini, Paolo
86 29 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.
87 1 Franchini, Paolo
88 29 Franchini, Paolo
* *Detector alignment*: chase Paul K. about the note review. Reproduce the equivalent plots present in the note for the data. Agreed on 4-5 pages.
89 1 Franchini, Paolo
90 30 Franchini, Paolo
* *Magnets*: tracker field note in progress; some work to do on the systematics. FC is the missing piece.
91 1 Franchini, Paolo
92 30 Franchini, Paolo
* *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.
93 29 Franchini, Paolo
94
* *Absorber model*: LH2 absorber validation stands. Waiting from Colin for measurements done for the safety case.
95
96
* *Diffuser study*: no updates.
97
98
* Agreed to show a first version of the plots during the imminent Warwick workshop.
99
* 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).
100 30 Franchini, Paolo
* Some contributions might end up in a separate stand alone paper.
