This C258400100018 facility served to produce 22Mg ions. C258400100019 (LINAC,1USAMSU) 22Mg ions were injected into the ReA3 C258400100020 reaccelerator and accelerated to 5 MeV/u C258400100021 SAMPLE Sample was an Active-Target time projection chamber C258400100022 (TPC) filled with mixture of 95% He and 5% CO2 at C258400100023 the pressure of 600 torr. The active volume of the C258400100024 TPC is cylinder of length 1 m and of a radius 29.2 cm. C258400100025 DETECTOR The time projection chamber was at the same time He C258400100026 target as well as the detector of reaction products. C258400100027 Cylindrical TPC is placed in uniform magnetic field C258400100028 of 1.9T produced by solenoidal magnet. The sensor C258400100029 plane consisted of approx. 10000 equilateral triangle C258400100030 pads which provided x-y information of the particle C258400100031 track. Drift time of the electrons provided C258400100032 longitudinal z component of the track. C258400100033 (IOCH) A thin ionization chamber placed in front of th C258400100034 TPC, filled with isobutane at 10 torr was used to C258400100035 record the beam intensity aand identified the beam C258400100036 contaminants. Signal from ionization chamber was used C258400100037 also for time reference of the TPC signals. C258400100038 METHOD Inverse kinematics was used. C258400100039 INC-SOURCE 22Mg was produced from the fragmentation of a 24Mg C258400100040 primary beam accelerated by the coupled cyclotrons C258400100041 and selected by the A1900 fragment separator. The C258400100042 22Mg fragments were stopped in gas cell and C258400100043 transported to electron beam ion source. The ions C258400100044 from ion source were injected to ReA3 reaccelerator C258400100045 and accelerated to cca 5 MeV/A with average beam C258400100046 intensity of 900 pps.
