November 3, 2005 Meeting with Bill Atwood, Eric Charles, Heather Kelly, Steve Ritz

While we were all at SLAC, we had a meeting concerning the work to be done on the ACD software.

The priorities where assigned are: H = High, M = Medium, L = Low.

Geometry

Activity

Description

Priority

Status

Overlaps

Crown. This also include overlaps of side tiles, which is dependent on shingling

M

Screws

The description for screws is already available, needs more testing

L

Curved top tiles

As agreed with ACD team, this will be implemented as an extra squared off piece

M

Shingling

Probably the most difficult update to the model

M

Check side tile edge wrt Si

Should talk to Leon

H

As Built Gaps

Is this possible before positon maps are available?

H

Blanket-MMS

Dave Thompson has provided up to date details

H

flexures

Need to consult with Alex to see if this is important

 

weighing support material

need to consult with Alex to see if this is important

 

BEA

need to consult with Alex to see if this is important

 

Joanne will not be available to help with geometry updates at least until after January.
Eric stated that by the end of January, he would be able to provide position maps of the detectors and gaps.

Digitization

Activity

Description

Priority

Status

Ribbon Attenuation

Alex has provided mean PE per MIP based on position along ribbon.

L

 

Fiber Attenuation

Alex provided a table before the AcdGeo simulations.

H

DONE

Check/Improve Edge Effects

 

H

 

Noise

Check the current std deviations

 

Overlays

what is this???

 

 

"Hit map" vs "Accept map"

 

 

 

Range

 

 

 

Left&Right Factor of 2 Check

A quick fix was inserted in the code to fix the factor of two, need to check to be sure there are no further instances.

H

 

CNO

Check handling from beginning to end.

 

 

readout limitations

i.e. an event causes 89 tiles to fire, but only 10 are read out - need to check to see what the default is

 

 

After some discussion, it was decided not to explicitly model pedestals in the MC simulation.

Reconstruction

Activity

Description

Priority

Status

Use of PHA

Calculating reconstructed ACD energy per tile

H

 

New Variables in merit

Introduce Eric's new TkrIntersect Quantities into the ntuple, they are in full recon.

h High, but Bill doesn't want to hold up DC2 for them.

 

Normalize Energy Deposition by Angle

 

M

 

Distances in tracking sigmas

Eric's new TkrIntersect code using the propagator should make this easy

M

 

AcdMaxTileE

Variable used by Steve to help eliminate S/C events.

H

 

Store both MC Enery dep AND Recon Energy

Currently only MC Energy Deposited is stored.

H

 

Angle beween recon track and tile plane

Requested by Alex.

H

Done. Pathlength through tile is stored in TkrIntersect

Store X,Y of Active Distance

Requested by Alex

H

Done. TkrIntersect provides Global X, Y position
