Analog wire chambers
Analog wire chambers are used on all beam lines in the SPS Experimental Areas.
These Multi Wire Proportional Chambers provide beam profiles, integrated over a full burst. There
are two types: XWCA and XWCM.
 |
Wire spacing: 1 mm
However, based on cabling, only every second or third wire can be read.
Hence the effective wire spacing is 1, 2 or 3 mm.
Sensitive area: 10 x 10 cm2
Often these XWCA chambers come with an IN/OUT motor, sometimes shared with a
Tigger counter |
|
Wire spacing: 2 mm
However, based on cabling, only every second or third wire can be read.
Hence the effective wire spacing is 2, 4 or 6 mm.
Sensitive area: 20 x 20 cm2
Normally XWCM chambers are notmotorised. |
There are presently three cases in the current hardware
implementation and should be covered by CESAR. Case 2 is
particularly important because it mainly concerns MWPCs from M2
line. At the time, they can be moved only from FESA.
- MWPC that are mounted on a Scintillator
support: Are still controlled by the
Scintillator server.
- MWPC that have their own motorization: An
new implementation of the movement through the
(2009) MWPC server.
- MWPC that are not motorized at all: This is
(or should be) stated in the application.
Which case for which analog wire chambers.
