  1. UNIFORMITY STUDY OF INO ICAL’S RESISTIVE PLATE CHAMBER BY HARIKRISHNAN.A INO DHEP

  2. Introduction • Scintillator is a material which emits light(scintillations) when an ionization radiation falls on it. • Plastic scintillator are used. • PMT(Photo Multiplier Tube)- A device which converts light into electric current. • Light guides are used to carry light from scintillator to PMT • Discriminator – An electronic circuit which converts analog signal to a digital pulse.

  3. Calculation Of Efficiency Delay is added(15ns) 2-fold ref1 Discriminator 1 ref2 Discriminator 2 3 -fold Test Discriminator 3 Efficiency= (3-fold/2-fold)*100

  4. Delay: One of the pulse is delayed to decrease time jitter in the coincidence pulse. • The threshold for both the reference paddle is set to -25 mV and the test paddle is set as -20 mV

  5. Calculation of Operating Point 2-fold Delay is added (15 ns) Ref 1 Ref 2 3 -fold Delay is added (20 ns) L Test 3 -fold Delay is added (30 ns) U Test Threshold for all the paddles were set as -25 mV

  6. Efficiency v/s voltage graph of test paddle 1 Efficiency Voltage (kV)

  7. Efficiency v/s voltage graph of test paddle 2 Efficiency Voltage (kV)

  8. Zonal Efficiency Of RPC • RPC is placed between two scintillators and will find the efficiency. • Our paddles have the area 10cm*10cm. Paddle 1 14 cm RPC 14 cm Paddle 2
