Dear All,

Just to let you know we just submitted the FST NIM paper to the arXiv, see the email below.

To submit to NIM, we will need to provide 3 suggested reviewers (required, see attached screenshot).

If you have any good candidate, please let me know the name and email address.

Best,

Xu

Dear arXiv user,

We have received your submission to arXiv. Your temporary submission
identifier is: submit/5729631.

You may update your submission at: https://arxiv.org/submit/5729631

Your article is currently scheduled to be announced at Tue, 16 Jul 2024 00:00:00 GMT.
Updates before Mon, 15 Jul 2024 18:00:00 GMT will
not delay announcement.

All submissions are subject to arXiv moderation, which may result in a delay.
Information about moderation is at: https://arxiv.org/help/moderation.
General information about submission status is at: https://arxiv.org/help/submit_status.

Your submission status is displayed in your user dashboard: https://arxiv.org/user/.
There may be a delay of an hour or more after the announcement time when the submission is
not visible while it is being processed by our system. When the process is complete the
public version of the work will appear.

After the announcement process you will be emailed a link to the paper. That email will
include a paper password that you should share with co-authors to allow them to
claim ownership.

The title and abstract will appear in the daily announcement mailings as displayed below,
except that the submission identifier will be replaced by the official arXiv identifier.

 The Forward Silicon Tracker (FST) is a pivotal component of the forward
upgrade of the Solenoidal Tracker at RHIC (STAR), designed to discern hadron
charge signs with a momentum resolution better than 30\% for $0.2 < p_T < 2$
GeV/c in the $2.5 < \eta < 4$ pseudorapidity range. Its compact design features
three disks along the beam direction, minimized material budget and scattering
effects. The FST uses Hamamatsu's p-in-n silicon strip sensors with a double
metal layer for efficient signal processing. The flexible hybrid boards,
essential for the readout system, are constructed with Kapton and copper layers
to optimize signal handling and power distribution. These boards connect
silicon strips to analogue pipeline ASIC APV25-S1 chips, which read up to 128
channels each. A cooling system with nonconducting, volatile NOVEC 7200 coolant
at 22.2{\deg}C mitigates ASIC-generated heat. The FST enhances forward tracking
performance at RHIC, showcasing unique design solutions to complex challenges.
