Inventory equipment

 Before beginning the installation process for the Fabry-Perot, it is recommended that you inventory the equipment, to make sure that all of the required parts are present. If you find something missing at this stage, there will be more time to rectify the problem. Regardless of the telescope being used, the Palomar crew will probably have removed the Fabry-Perot equipment from the first-floor equipment room at the 60-inch telescope dome and placed it on the observing floor. The equipment should consist of:

$\Box$

One large, black fiberglass case, containing the Fabry-Perot instrument body.

$\Box$

One large wooden crate, containing the Fabry-Perot etalon controller.

$\Box$

One medium wooden crate, containing all of the pieces necessary for assembling and operating the instrument. This crate is marked, ``shutter controller''. These include:

$\Box$

nitrogen regulator

$\Box$

small plastic box of screws and related hardware

$\Box$

pair of etalon mounting plates (for ET-50 and ET-70 etalons)

$\Box$

58 mm and 105 mm Nikon lenses in their original boxes

$\Box$

focus rings for each lens

$\Box$

instrument tube extension ring

$\Box$

small curved focus plate

$\Box$

small cubical cable boot box

$\Box$

pair of boot box cover panels

$\Box$

small plastic box containing a Neon lamp

$\Box$

small brown power supply for the Neon lamp

$\Box$

small cardboard box containing a shutter (P-200 only)

$\Box$

silver shutter controller unit (P-200 only)

$\Box$

two 3-inch filter holders and plastic screws (P-200 only)

$\Box$

One small wooden crate, containing all of the cables for the instrument. These include:

$\Box$

nitrogen hose

$\Box$

etalon controller power cable

$\Box$

etalon controller RS-232 cable

$\Box$

6-foot and 39-foot etalon cables

$\Box$

cardboard box containing a pair of short-haul modems (P-200 only)

$\Box$

One small silver briefcase, containing the etalon.

$\Box$

One cardboard box, containing a number of little-used components (e.g., the 135 mm collimator, a Hydrogen lamp, etc.).

In addition to these Fabry-Perot components, you will need a few general items:

$\Box$

Small wooden box of ``Narrowband Filters''. This box is kept in the 60-inch dome equipment room.

$\Box$

3 coax cables (200-inch only). These are used for connecting the etalon controller to the Microvax and for the shutter control line. Coax cables of a number of lengths can be found hanging on the wall in the astronomer's workshop, adjoining the main observing room at the 200-inch telescope.

$\Box$

Variable power supply (200-inch only). This power supply is used to regulate the input voltage to the shutter controller, and can be found on a shelf in the 200-inch electronics lab.

Check to be sure that all of the primary pieces of the instrument are present, and that the equipment is situated near a work table, where the Fabry-Perot may be assembled.
