Step into the World's Largest Digital Camera

The LSST camera’s enormous field of view and highly-sensitive image collectors make stable focus critical. The required precision creates new technical challenges.

The camera team for the Large Synoptic Survey Telescope will join heads in a three-day workshop the week of September 15th for their last major colloquium before tough agency reviews next spring. A collaboration of 15 institutions and 70 people, the team will review tests of camera element prototypes and explore what’s needed to attain the precision and coordination required for the largest digital camera in the world.

The size of a Smart car and mounted at the center of the telescope’s secondary mirror, the camera employs two lenses to focus light through a filter, shutter and final lens—doubling as a vacuum seal—to the heart of the camera, its detector plane. This 65-centimeter diameter mosaic of silicon detectors dwarfs previous telescope focal planes. It will allow the camera to capture a larger fraction of the sky in one shot than anything in existence. The detectors themselves will address a blind spot in current technology’s view of the electromagnetic spectrum: the transition between infrared and very red visible light, at 9000 Angstroms to 1 micron.  Read more...

Blood Drive Wednesday: Give a Pint, Get a Pint

(Logo)SLAC will host a blood drive in the Panofsky Auditorium Lobby on Wednesday, August 27, from 8:00 a.m. to 3:00 p.m. This drive is open to all members of the SLAC community and the general public.

Each donor will receive a coupon for a free pint of Baskin-Robins ice cream.

To donate blood, you must:
- Be 17–74 years of age
- Weigh at least 110 pounds
- Be feeling healthy
- Be well hydrated
- Eat within 6 hours prior to donation
- Bring photo identification

To schedule an appointment online, log onto the Stanford Blood Center Web site and click "Find a Blood Drive." Under "Search by Sponsor Code" enter sla5323 in the box and click "Find Blood Drive." Click on the date of the drive, then follow the prompts to schedule your appointment.

Appointments will be given priority, but walk-ins are always welcome!

See SLAC's blood drive Web page for more information. Please contact Lauren Barbieri with questions.


Public Lecture Tuesday

Join UC Berkeley physical bioscientist Vittal Yachandra tomorrow at 7:30 p.m. in Panofsky Auditorium for "How Plants Do It: Light, Oxygen, Action!" As part of the SLAC Public Lecture series, Yachandra will highlight the lessons plants can offer through their generation of energy and oxygen from water and air.

A Younger, Healthier Back

Wednesday from noon to 1:00 p.m., the Women's Interchange at SLAC presents pain expert and posture specialist Esther Gokhale in "Sit Your Way to a Healthy Back." Gokhale will discuss the use of natural, healthy posture to ease back strain and pain. Join WIS in the Redwood Room, A and B, in the Research Office Building (Bldg. 48). (Please note the change from the usual venue.)
