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
- 1
Note that the blade names here may be different than the EPICS support. The difference is to make the names of the blades consistent with other slits with the Bluesky framework.
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)
