Abstract

The STAR experiment at RHIC is planning to upgrade the Time Projection Chamber which lies at the heart of the detector. We have designed an instrument to measure the tension of the wires in the multi-wire proportional chambers (MWPCs) which will be used in the TPC upgrade. The wire tension measurement system causes the wires to vibrate and then it measures the fundamental frequency of the oscillation via a laser based optical platform. The platform can scan the entire wire plane, automatically, in a single run and obtain the wire tension on each wire with high precision. In this paper, the details about the measurement method and the system setup will be described. In addition, the test results for a prototype MWPC to be used in the STAR-iTPC upgrade will be presented.

MWPC prototyping and performance test for the STAR inner TPC upgrade

Journal Article Shen, Fuwang ; Wang, Shuai ; Kong, Fangang ; ... - Nuclear Instruments and Methods in Physics Research. Section A, Accelerators, Spectrometers, Detectors and Associated Equipment

A new prototype of STAR inner Time Projection Chamber (iTPC) MWPC sector has been fabricated and tested in an X-ray test system. The wire chamber built at Shandong University has a wire tension precision better than 6% and wire pitch precision better than 10 μm. The gas gain uniformity and energy resolution are measured to be better than 1% (RMS) and 20% (FWHM), respectively, using an ⁵⁵Fe X-ray source. The iTPC upgrade project is to replace all 24 STAR TPC inner sectors as a crucial detector upgrade for the RHIC beam energy scan phase II program. Furthermore, the test resultsmore »« less

Particle identification studies with a full-size 4-GEM prototype for the ALICE TPC upgrade

Journal Article Aggarwal, M. M. ; Ahammed, Z. ; Aiola, S. ; ... - Nuclear Instruments and Methods in Physics Research. Section A, Accelerators, Spectrometers, Detectors and Associated Equipment

We present that a large Time Projection Chamber is the main device for tracking and charged-particle identification in the ALICE experiment at the CERN LHC. After the second long shutdown in 2019/20, the LHC will deliver Pb beams colliding at an interaction rate of about 50 kHz, which is about a factor of 50 above the present readout rate of the TPC. This will result in a significant improvement on the sensitivity to rare probes that are considered key observables to characterize the QCD matter created in such collisions. In order to make full use of this luminosity, the currentlymore »« less

Memorandum of Understanding for the 2007 Meson Test Beam Program: STAR Muon Telescope Detector

Technical Report Xu, Zhangbu

The experimenters propose an R&D research on a large-area and cost-effective muon telescope detector (MTD) for RHIC and for next generation detectors at future QCD Lab from state-of-art multi-gap resistive plate chamber (MRPC) with large module and long strips. Conventional muon detectors rely heavily on tracking stations while this new R&D project proposes to use good timing and coarse spatial resolutions to identify muons with momentum of a few GeV/c. This R&D project was approved as BNL LDRD (Lab Director R&D) project and will focus on studying the capability of muon identification based on timing resolution from the MRPC detectormore »« less

The STAR BES-II and Forward Rapidity Physics and Upgrades

Conference Yang, Qian ; Arkhipkin, Dmitry

The second phase of the Beam Energy Scan at RHIC, BES-II, is scheduled to start in 2019 and will explore with precision measurements the high baryon density region of the QCD phase diagram. The detector upgrades will enhance some of the key measurements by extending STAR’s kinematical reach. Examples are the kurtosis of net-protons, which could pinpoint the position of a critical point. The upgrades currently under way comprise: the replacement of the inner TPC sectors, the Event Plane Detector and the end-cap TOF. Building on these upgrades STAR is planning to further enhance its detector capabilities by installing amore »« less

Sensitive and simple method for measuring wire tensions

Technical Report Atac, M ; Mishina, M

Measuring tension of wires in drift chambers and multiwire proportional chambers after construction is an important process because sometimes wires get loose after soldering, crimping or glueing. One needs to sort out wires which have tensions below a required minimum value to prevent electrostatic instabilities. There have been several methods reported on this subject in which the wires were excited either with sinusoidal current under magnetic field or with sinusoidal voltage electrostatically coupled to the wire, searching for a resonating frequency with which the wires vibrate mechanically. Then the vibration is detected either visually, optically or with magnetic pick-up directlymore »« less
