Dear Xu,

please find below the abstracts with some small corrections, with them implemented forward the abstract to STAR talks.

Cheers elke

The STAR Collaboration at RHIC plans to install a suite of new detectors in the forward rapidity region (2.5 < η < 4.0), enabling a program of novel measurements in pp, pA and AA collisions after the Beam Energy Scan Phase II. This upgrade comprises new electromagnetic and hadronic calorimetry, and a new Forward Tracking System (FTS) which consists of a Forward Silicon Tracker (FST) and a Forward small-strip Thin Gap Chambers (sTGC). The FST is essential to discriminate the hadron charge for transverse asymmetry studies and separating electrons and positrons for Drell-Yan measurements.

In this talk, we will present the design and the construction status of the FST, together with the mechanical support and integration plan. We will also briefly discuss the performance studies of the FST prototype modules in  cosmic ray and laser tests. 

Gavin Wilks

The STAR forward upgrade comprises a Forward Silicon Tracker (FST) based on silicon strip sensor technology, providing track reconstruction for charged particles with full azimuthal coverage in the rapidity range of 2.5<y<4. The FST prototype modules were tested with and calibrated with cosmic rays, using Inner Silicon Tracker (IST) staves for track alignment. Detection efficiency and position resolution of the prototypes were measured, and their dependencies on operating conditions and clustering algorithms were studied. Since track reconstruction is contingent on the efficiency and resolution of individual FST modules, more realistic predictions of charged particle detection with the FST can be produced from MC simulation using the results measured with the prototypes. In this talk, we will discuss the cosmic ray and simulation studies with the FST prototypes.

Hi all,

UIC group plans to submit two abstracts for the DNP meeting from me
and Gavin Wilks.
Gavin Wilks is a graduate student at UIC. He has been working with
Zhenyu and me on cosmic ray data taking and analyses.

My abstract is focusing on the overall status STAR FST Upgrade status.
And Gavin's abstract is about cosmic and simulation studies of FST
prototype performance.

Please find two abstracts in the following link:

Comments and suggestions are welcome.

Best,

Xu

Dear all,

Please see Elke's request in the following. I think it is a good opportunity for Xu or Shenghui?

Cheers,
Yi

Dear All,

I have not yet seen abstracts from this group for DNP.
I think we should have the abstracts on the following topics
- one on the silicon
- one on the stgc
- one on the calorimetry
- Hannah on her analysis
- Xilin on his pi0 analysis
- one on tracking

and of course if there is any other idea for a presentation it is very welcome

Cheers elke
