EPICS synApps optics 2slit.db#

db_2slit: synApps optics 2slit.db

There are two implementations, corresponding to differing and competing opinions of how the support should be implemented.

Coordinates of Optics2Slit2D_InbOutBotTop (viewing from detector towards source):

   top
inb   out
   bot

Coordinates of Optics2Slit2D_HV (viewing from detector towards source):

    v.xp
h.xn    h.xp
    v.xn

Each blade [1] (in the XIA slit controller) travels in a _cartesian_ coordinate system. Positive motion moves a blade outwards (towards the p suffix). Negative motion moves towards the n suffix. Size and center are computed by the underlying EPICS support.

hsize = out - inb vsize = top - bot

USAGE:

slit1 = Optics2Slit2D_HV("gp:Slit1", name="slit1")
slit1.geometry = 0.1, 0.1, 0, 0  # moves the slits
print(slit1.geometry)

slit2 = Optics2Slit_InbOutBotTop("gp:Slit2", name="slit2")
slit2.geometry = 0.1, 0.1, 0, 0  # moves the slits
print(slit2.geometry)

“sync” is used to tell the EPICS 2slit database to synchronize the virtual slit values with the actual motor positions.

Added in version 1.6.0.
