Hartmann Wavefront Sensor (HWS) delta-preliminary design review (PDR) documentation

Document #:
Document type:
T - Technical notes
Other Versions:
The overview preliminary design document is given by this record ID number. It describes the aLIGO HWS at a delta-PDR level. (PDR for the HWS was part of the TCS review in 2009; see T0900304.)

Additionally, documents linked to this record encompass material recommended for complete review of the preliminary design phase (per M050220).

Staffing -
A collaboration between the University of Adelaide (UA) and Caltech has been formalized under LIGO-L1000201-v1, whereby the majority of software development is taken on at UA and the balance of development takes place at Caltech.

Cost -
The updated cost book for HWS appears in M1000349

Schedule -
The earliest need date for HWS integration is Sept. 2011 for H2 at HAM10. Prior to this time, some HWS components (embedded in ALS) will be integrated at BSC6 of the H2 y-arm.
