Support Activities for the LAT PDR (Fall 2001)

Steve has laid out the requirements for our support of the LAT PDR. Basically we need to re-evaluate the the instrument performance and background rejection capabilities.

This web provides a focal point for the support activities, and is a work in progress.

So far, there will be weekly vrvs meetings, Tues 10:00 AM PST, with minutes.

Planned Activities ("The Plan")

The Code

Look at the top-level package, pdrApp.  Here is a FAQ providing answers to common questions about using pdrApp.

Geometry Details:

ACD        Thermal Blanket

Numbering

Prompted by JJ Russell's request, the subsystem folks have verified that their system conforms to Steve Ritz's memo, in terms of numbering. This is also the case for numbering the towers. The exception is the CAL (which will be fixed to adhere to the standard!), from Eric:

The numbering scheme in the IRF is as follows:

1. Layers are numbered 1 to 8 from bottom to top, i.e. layer 1 has a more negative Z than layer 8.

2. Within a layer, the log number increases with increasing X or decreases with increasing Y. The log number runs from 1 to 12.

3. Tower numbering runs 0 to 15, but I don't know whether it counts faster in X or Y.

Analysis and code Development: 

See a list of packages and their states

We hope to support the following environment for study of the results and/or development of new algorithms

• ROOT

• Gaudi - see the package userAlg

• IDL

ntuple

Currently, pdrApp produces a Root ntuple that can be analyzed within Root or from userAlg.  

• description of the current ntuple

• sample Root macro to read the ntuple and make plots.

For historical descriptions

• description of the current contents of this ntuple.

• AO version, perhaps more recent.

• a list of the required elements.

Event Processing

• Log of test datasets

• Log of datasets for 5 M event SLAC Linux farm PDR background warmup

• Log of datasets for initial 50 M event SLAC Linux farm background run

• Log of datasets for initial 1 M event SLAC Linux farm all gamma run

• Log of datasets for latest 1 M event SLAC Linux farm background test run (pdrApp v7r1)

• Log of datasets for latest 50 M event SLAC Linux farm background run (pdrApp v7r1)

• Log of datasets for latest 1 M event SLAC Linux farm all gamma run (pdrApp v7r1)

After PDR?

We have started to compile a list of "To Do" items for after the PDR.
