4. Chuck H. is handling H2_RG mounting and necessary dewar mods contingent on an acceptable H2_RG detector becoming available Chuck H. WIRC-POL SOW: SOW_Chuck_Henderson_7_14_16.docx Schedule of WIRC-POL optomechanical upgrades (basis for CH SOW): WIRC-POL_schedule_7_14_16.xlsx |
Precision Cryogenic dewar drawings have been used to partly convert 2-d hardcopies to SW CAD models in the vault under:WIRC->WIRC-POL->WIRC-POL Preliminary Design-> and Precision Cryogenics 2-D hardcopy drawings were scanned into file: PC_WIRC_Drawings.pdf |
Task | Status |
1. Two-position focal plane mask for: a. full-FOV (current configuration) b. reduced FOV (reduce background behind spectro/polarimetric traces) |
Bi-stable Mechanism preliminary design complete in the SW Vault under: WIRC->WIRC-POL->WIRC-POL Preliminary Design->06_30_16FieldStop mechanism.SLDASM Mechanism actuator, either push pull solenoid or stepper motor (precise actuation unnecessary due to bi-stable design) is still required. the current design was presented at the PDR on 7/22 |
2. Zemax modeling for verifying optomechanical design decisions (e.g.,* WIRC-POL_PG_AOI_7-8-16_weekly_meeting.pdf : Pol. Grat AOI Zemax ) | Current .zmx for WIRC-POL upgrade 4quadrant_WIRCPOL_diff_grat_Lens_arry_7deg.zmx and 4quadrant_WIRCPOL_diff_grat_Lens_arry_0deg.zmx : originally an interim version until IUCAA model is provided (still awaiting). The above non-sequential Zemax files for determining ghosting are the most current as of 7/22. |
3. Chuck H. is handling mods to filter wheel to accommodate the GRISM & PG and provide 1.0 milliradian clocking alignment:
|
Telic optics drawings are partially converted to SW CAD models in the vault under: WIRC->WIRC-POL->WIRC-POL Preliminary Design->COLD-COL-WIRC-OPTICS.SLDASM. Chuck has done some investigation to verify that a design based on limit switches (of a specific type) will be sufficient for providing the 1 mrad required filter wheel orientation tolerance.
