We are continuing the acceptance and development tests on the telescope begun in July, 2000. The work originally planned for the trip scheduled for January, 2001, had to do with mainly with putting the secondary mirror into the telescope and testing the telescope as a Cassegrain system with secondary emphasis on continuing to develop the telescope control system. All thas work was contingent on getting the secondary back from Torus Optics, which we could not do in time to do the work in January. Consequently, most of the work we did on the trip of 23-28 January had to do with minor additions to the control system. The weather was clear for the first few nights, but it snowed for the last two nights we were there.

The work planned falls into four categories as follows:

1. MECHANICAL ADJUSTMENTS and augmentation of the telescope structure.
1. Decide on any modifications to the base skirt needed to keep it from rubbing and make them. (We didn't have time to do this because we had to take the skirt off to add more zero-point sensors.)
2. Put in place stands for camera to observe telescope and timer for oil pump. (We put these stands in place the first day.)
3. Straignten up wiring on top of telescope, run wire to the camera in the instrument head, put handles on cover for back of central cone, armor control/instrumentation cables, and put airducts on top of telescope. (We added handles and holes with rubber gromets to the covers for the back of the central cone and put the covers back on the telescope. These holes will allow the wire for the camera and fiber leads for the spectrograph to pass out of the telescope tube. We also connected the two halves of the airducts for the pump house and back wall but did not put them in place.)
2. ELECTRICAL WIRING.
1. Rewire pump motors for 220V and get them on the protected power. (We finally got the oil pumps rewired for 220 V on protected power and wired the sensors for high oil temperature and low level into the control system.)
2. Wire limit switches (to test for closed roof and front flap) into the control system to test for interference with the telescope enclosure and test them. (We wired these switches into the building and checked their function with a ohm meter. One sensor for the rolling roof still requires a permanant shim next trip.)
3. Set up the optical sensor designed to protect the telescope from having the enclosure hit it and wire that sensor into the roof controller. (We set this sensor up and checked its function. It requires a special mount to get it out from under the moving roof when the building is closed. This sensor will be wired into the building-control computer.)
4. Add more magnets for the Sony home switch (in azimuth) and integrate these new home positions into ther control system. (We added five more magnets to give a magnet every 60 degrees in azimuth. We then measured their positions, added them into the control system, and tested the control system by finding stars.)
3. Work on the DRIVES and CONTROL SYSTEM.
1. Run rests to verify new routines for a) moving the secondary mirror and instrument head, b) turning on the oil pump and reading its status, and reading the status of the enclosure before a slew and responding to it. (We ran the tests on the secondary mirror in the lab and ran the other tests at the telescope.)
2. Run further acceptance tests for motions in instrument head. (We ran these tests in the lab before going to Arizona.)
