Transcript of Short Introduction to MuTr at PHENIX BY AHMED AL-JAMEL NEW MEXICO STATE UNIVERSITY 2002
MuTr at PHENIX
● MuTr stands for Muon Tracking.● The MuTr subsystem has two arms:
North and South.● Both arms are completely installed
now. The North was recently installed, and will be used for the first time in RUN-03.
Components of Each arm
● Each arm has three stations: [1]. Station 1 [2]. Station 2 [3]. Station 3 Interaction
region IR
S3
S2
S1
Station 1● Station 1 is divided into
four quadrants
● Each quadrant has three gaps : gap1, gap2 , gap3
● Each gap consists of an anode plane sandwiched between two continuous cathode planes.
● Thus in each quadrant, we have 6 cathode planes
● --> 3 hit points (6 -coordinates) from Station 1.
A quadrant
Station 2, S2● Station 2 is divided
into 8 octants, or chambers.
● Each octant has 3 gaps: gap 1, gap 2, gap 3.
● Each gap consists of an anode plane sandwiched between two continuous cathode planes.
● -----> 3 hit points from S2.
An octant from S2
Station 3, S3 (The biggest)
● Station 3 has 8 octants● Each octant has two
gaps: Gap 1, Gap 3.● Each gap consists of
an anode plane sandwiched between two cathode planes.
● ----> 2 hit points .
Some octants of S-3 while they were comissioned in 905.
MuTr SubsystemsThese are the top MuTr operating systems:
( PLEASE SEE THE STANDING ORDERS OR THE MUON HOMEPAGE TO LEARN MORE!)
----------------------------------------------------------------
● High Voltage HV : ~ 1825-1850V on the anode wires.
● Low Voltage LV : For the electronics and cameras.
● Gas System: To mix and supply the gas to the chambers.
● Front End Electronics FEM: To read the signals from the cathodes ----> DAQ.
● Optical Alignment System OASys: To monitor the relative motions of the chambers ...
● Others: water flow through hoses to keep the temperature of the FEMs low. Air tubing, to reduce the humidity. Also, and without doubt, the lamp shades (magnets)
High Voltage GUI
● How to read from this GUI: Example: N341 means North, S3, Oct4, gap1.
Currents
Voltage
Physics
● Looking for peaks of j/psi from Dimuon analysis
● Heavy Quark production via Single High Pt muons...
● Others, of course, in the muon webpage....
