Online QA Rate Limitations

Under:

Some interest has been expressed to obtain increased statistics for at least some quantities shown in the Online QA plots.

5) Evaluation of BSMD dynamic range needed for the W program at STAR, ver 1.0

Under:

M-C  study of BSMD response to high energy electrons

 

16 correlation of MIP ADC vs. raw slopes

Under:

 Scott asked for crate based comparison of MIP peak position vs. raw slopes .

I selected 100 consecutive BPRS tiles, in 2 groups, from each of the 4 crates.

Replication monitoring

Under:

Following tools are available for replication check:

Server list and various parameters

Here will be a server list (only those servers participating in various replication scenarios)

15 Broken BPRS channels ver=1.6, based on data from March of 2008

Under:

 The following BPRS pmts/tiles have been found broken or partially not functioning, based on reco MIP response from pp 2008 data.

 

14 ---- MIP gains ver=1.6 , 90% of 4800 tiles ----

13 MIP algo, ver=1.1 (example of towers)

Under:

This is an illustration of improvement of MIP finding efficiency if ADC gates are set on BPRS & BTOW at the places matched to actual gains instead of  fixed 'ideal' location.

12 MIP gains ver1.0 (all tiles, also BTOW)

Under:

 This is still work in progress, same algo as on previous post.

Fully Corrected Yields

 Ok, now we're cooking.  Most of the ingredients are in place.

Reconstruction and Trigger Efficiency Correction Factor

 Now that I have my raw pion spectrum (see here) I need to proceed

Jigsaw Inv Mass Plots (final)

 As noted here and here, the pion peak is difficult to model using single-particle MC.  In single particle studies, the pion inv mass peak is reconstructed to narrow.
