1 1  4 alignment laser units are located in the experimental hall. They are sketched in the overview (see figure below for details). Please note that the units at BL3 and BL1 are equipped with additional features. BL3 has integrated a powermeter whereas BL1 is provided with two filters.

25 +== The laser can be controlled via jddd: ==
26 +
27 +* the laser can be switched on and off (on / off buttons) with a "mini-Beckhoff" control switching on and off the power for the laser. more see below
28 +* to see the laser a mirror has to be inserted to reflect the laser into the beamline. this is controlled via a sincos driven stepper motor connected to the VLS motor control. this server can be restarted in the "expert tab"
29 +* The direction of the laser can be changed using a 2 Picomotors mounted on a mirror holder allowing to steer the direction in fine steps.
30 +** the picomotor server can be restarted from the expert tab
31 +** the picomotor controller can also (in case it is completely stuck ) be power cycled from the expert tab

49 +The Box has 8 24 V outputs.  They are connected to:
50 +
51 +* for the BL1/BL3 laser to a home build (FS-EC) box that controls the 240V lines (the 240 V go in cables from the box to the Lasers / Picomotors)
52 +* for the BL and PG laser to a [[home build (FS-EC) box>>doc:FLASHUSER.jddd-linked help pages.Alignment Laser Units in the FLASH1 Hall.BDAAlignmentLaserBox.WebHome]] that produces 5V / 15 V using relais that power the laser / picomotor controllers directly
