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)

EPICS synApps optics 2slit.db 1D support: xn, xp, size, center, sync
“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.
