Receiver issues

---------------

Wolfgang Wild and John Payne, 6 March 2000

1. Confirmation of frequency bands

2. 30 GHz band

3. Choice and priority for initial bands (U.S.: 3 mm, 1 mm, and 0.5 mm, EU SAC: 3 mm, 0.8 mm, and 0.5 mm)

4. Requirements for 183 GHz water vapour monitor: alignment with optical axis stability switching arrangement sensitivity

5. Total power stability of all receivers. What is the scientific requirement over what time scale ? For what observing mode ?

6. Calibration requirements: accuracy of amplitude calibration

7. Polarization requirements

8. Current understanding of switching requirements: band to band 1.5 sec within band 10 sec

Single dish antenna frequency switching: 0.03% freq throw 10 msec

2:00-2:30 Report on Polarization (Dick Crutcher)

    Directions from the Kasteel Oud Poelgeest, Oegstgeest conference centre to the Leiden Observatory, J.H. Oort Building, Niels Bohrweg 2, Leiden.

    If you prefer to walk rather than take a taxi it will take you between 15-20 minutes. The lab is near the bottom left corner of the map sent to you earlier. From the conference centre walk down to the main road and turn left (Laan van Oud Poelgeest). Straight on at the roundabout. (The name of the street changes to Warmonderweg. Continue straight on and at the T-junction straight across into a narrow one way street Nachtegaallaan. Continue on and walk along the path at the end of this street, passing on your right first a wooden building with children's play equipment outside and then further down horse riding stables. You are now at the roundabout on the Wassenaarseweg. Cross the road and turn right walking along the Wassenaarseweg. You will see a tall chimney stack coming up on your left. Take the second left - Niels Bohrweg and the entrance to the J.H. Oort Building is across a bridge through the car park on your left hand side. There you will find the Reception desk. The Observatory occupies floors 4 and 5 as well as the 5th floor of the Huygens Laboratory which is joined to the Oort building.

    FOR DIRECTIONS AND MAPS FROM THE TRAIN STATION TO LEIDEN OBSERVATORY, SEE ITS WWW PAGE

    SUGGESTIONS FOR RESTAURANTS IN LEIDEN (French/Continental):

    (ask taxi driver to take you there or walk from Mayflower hotel)

    - Jill's restaurant: popular with live music on some evenings Morsstraat 6

    - Restaurant La Cloche: best French restaurant in town, but also most expensive Kloksteeg 5

    - Restaurant Het Prentenkabinet: nice setting in old mansion next to Kloksteeg 25 Pieterskerk and plaque of Pilgrims fathers

    - Fabers Restaurant Kloksteeg 13

    - Restaurant Koetshuis-de Burcht: nice setting at foot of old fort in Burgsteeg 13 center of town

    There are many other types of cuisine (Italian/Pizza, Greek, Chinese, Spanish/Argentina, etc.) in restaurants scattered throughout Leiden.
