HRIBF Information for PAC-6e
Proposal deadline extended to September 17, 2001!
As announced in the last HRIBF Newsletter ( Spring Supplement 2001) proposals to be submitted to the Program Advisory Committee must be received on or before September 17, 2001. Detailed instructions including important dates may be found on our website. Beam intensities may now be estimated as a function of beam energy and measured intensities injected into the tandem. The calculator is accessible from the tabulated RIB intensities. Information on major experimental endstations and on neutron-rich experiments may be found in previous HRIBF Newsletters. The membership of PAC-6e is also available.
We ask that you need to be aware that scheduling experiments at our facility is difficult. In some cases such as transfer experiments, our first RIB experiment will take place this summer. This ion source will be the first which we will have removed for storage with the intent of reusing it at a future date. There are no guarantees that this will be successful and a three week delay will result if it is not.
Additional information reflecting the present status of equipment and techniques is provided below.
- Silicon strip detector array for HyBall
- A 288-channel silicon strip detector array is presently being constructed and will undergo commissioning tests during the next scheduling period. Compatible with the present CsI detector array (without the forward two rings of detectors; 7-29 degrees in the lab), this system may be used in dE-E telescope configuration with 150 and 400 micron thick detectors. At present, we do not think this device will be ready for this ePAC.
- Windowless gas target system
- The windowless gas target system has undergone offline tests and has attained a thickness of 5x1018 He atoms. Tests and ES&H reviews will need to be completed before hydrogen gas may be used and the system available for outside users. It is not anticipated that we will accept experiments requiring this system.
- DRS commissioning
- The DRS will undergo further commissioning tests during this period to improve the overall system transmission and to test new configurations of the target station (including the windowless gas target system) and focal plane components.
- Microchannel plate plus foil detectors
- We are in the process of acquiring more microchannel plate (MCP) detectors for use as beam counters (suitable up to 1-4 MHz) and position sensitive focal plane detectors. In some cases, these detectors are built with removable foils so that they do not adversely impact beam quality when not needed.
