CORTO
CORTO (2013)
Structure: 1) two positional sensitive strip gas detectors (MRPC) (1 m x 2 m x 5 cm), which provide the track reconstruction.2) read-out electronics: NINO Application-Specific Integrated Circuits (ASIC), WaveCatchers, interface cards.3) gas supply system for MRPCs.
Main task is to reconstruct muon tracks.

Last results (2013)• A time resolution of 250 ps (for a bias
voltage of 16 kV), coordinate resolution along the X direction of 1.8 cm and along the Y direction of 2.1 cm.
Last configuration:
- Two MRPCs.
- One read-out board of WaveCatcher (48 channels).
- Signals rate is ~ 100 Hz for coincidences
between those two MRPCs.

Problems• Too high rate of MRPC signals (should be ~ 50
Hz).• Not nominal time resolution (should be ~ 100
ps).• Not uniformly distribution of efficiency on each
MRPC:
Reconstructed hits from bottom MRPC (2013).

Upgrade
1. In 2014 was added third MRPC for CORTO.
2. Three boards of WaveCatcher (total number of the channels is 48 x 3 = 144).

ConclusionDuring this year we have done a lot of
important steps for CORTO improvement:
Third MRPC, Three WaveCatcher cards, 2D SDC
All this things will help us to prepare the CORTO for it’s main mission – to test different types of detectors, knowing MRPC accuracy and efficiency.
