Participation of the Joint Institute for Nuclear Research (Dubna)
in the Future GSI Facility Possible JINR Contributions: Magnets of
SIS100 CBM Experiment PANDA experiment New projects (spin-physics,
antihydrogen, mesoatoms, etc.) JINR interests at GSI: Accelerator
Physics Nuclear Matter Physics with Antiprotons Applications 5
Excited glue (glueballs and hybrids) Charm in Nuclei, Charmonium
Hadrons in Matter Hypernuclei, etc. Using the ALICE experience the
JINR team is capable to design and construct the magnet system
(superconducting solenoid and conventional dipole) for PANDA And
also make contributions to the PANDA detectors: DIRC (Rich
detector) MDC (Mini Drift Chambers) Muon Detector Straw Detector
Forward RICH PANDA Experiment 6 Superconducting Solenoid (2T) and
DM with water cooled winding (2 Tm) 7 Cross-section of the dipole
magnet Cross-section of the solenoid 8 JINR team opportunities and
actions On-site coil winding facilities (solenoid & dipole) are
available; On-site cryogenic facilities to test coils are
available; A number of enterprises contacted in contest of the
construction PANDA magnets: MKB Raduga, Energomash, MKB Fakel, NPO
Lavochkin, NPO GELIYMASH; Management of Russian Ministry of
Industry dealing with the conversion of the military industry has
contacted to provide government support to build magnets in Russia.

Participation in DIRC JINR group (in collaboration with KBSU
(Nalchik) and FGUP GRAN) intends to take part in R&D on MCP
PMT. The R&D will include improvements in MCP PMT
manufacturing, development of new photocathode and readout
techniques. New type of photon detectors Si-MCP, based on
photolithographic masking of the channel pattern on the Si surface
are on consideration also. These newly emerged Si based MCP could
open completely new possibilities in the photon detector
technology. Fused silica/quartz from Russian industry as a base
material for DIRC radiators will be tested. 12 Photon Detectors 13

17 Muon Tracker for PANDA Previous JINR/DLNP Lab experience in
technology: DELPHI (CERN/LEP), D0 (FNAL/Tevatron), COMPASS
(CERN/SPS) Muon tracker based on Iarocci tubes' modification:
Mini-Drift Tubes (MDTs) Main purpose: L2/L3 muon trigger/filter
with precise muon pattern ID Total for PANDA: MDTs detectors (wires
& strips r/o), TDCs channels, FADCs channels Estimated cost
(joint Dubna/Torino resources): about 1 M Euro, (f/e electronics
requires additional evaluation) MDTs production rate at JINR
central workshop detectors/day, so matches reliably PANDA'
construction timetable 18 Central Tracking Detectors example event:
pp f f 4K Straw-Tubes: 15 skewed double-layers 19 Forward RICH The
RICH for PANDA is optimized for the particles identification in the
momentum range from 0.6 GeV/c up to 10 GeV/c and an angular range
1- 22. 20 Forward RICH The design of the forward Ring Image
Cherenkov detector with achromatic and short focusing optics has
been considered and detailed simulation is performed Optical Scheme
The proposed RICH scheme is fitted well to the PANDA setup and
provides excellent PID features Research of optical materials and
the photo- detectors for the RICH is in progress. 21 Possible
