Phobos Magnet Field Measurements at BNL

Magnetic field for negative arm finished!

Tuesday, February 16, 1999: We finished doing the fine grid magnetic field map for the nominal current setting of 3600A for the negative arm. Below you will find a picture of the three magnetic field components for the mid-plane (there were five of these planes). The grid size of the map is 1" x 1" x 2", the coordinates have not yet been translated into Phobos coordinates.

Preliminaries

Friday, January 29, 1999:

We started to do the Phobos magnetic field  measurements.

Here are the very first results for a 45 deg trajectory going from the nominal IP at full field. The measurements were done with a hand probe and are for the vertical direction only (By component):

 

Similar measurements were done for different current settings. These will be put on the web shortly. Based on these results, a selection will be made by Mark Baker what the nominal operating current will be.

Stay tuned!
