141.211.198.90:

JDM: Location-based configuration files. So if one takes the ipad into different labs then a different set of panels are automatically made available.

JDM: labels might be 'floating' rather than only living inside a tile. would allow for more aesthetically pleasing layouts and description.

===Full Alignment===

1.) Turn on the CHAMP alignment laser 
2.) Align each beam on R1 target using A0 
3.) Align on L1 using A1 
4.) Put blocker on R1 (using L1/L2-target), so you don't see two spots 
5.) Align on R2 using A2 
6.) Put blocker on L1 (using the R1/2-target) 
7.) Align on target L2 using A3 
8.) Remove the current blocker from L2 for alignment of Towers of Power 
9.) Align on Towers of Power 3 and 4 using L1-L6 mirrors 
10.) Remove current blocker on L1 
11.) Put blocker on R1 (using R1/R2-target) 
12.) Put blocker on Towers of Power 3-4 
13.) Align on Towers of Power 1 and 2 using R1-R6 
14.) Put blocker on Towers of Power 1-2 
15.) Align Towers of Power 3-4 (L1-L6) --- DUPLICATE ? 
16.) Put blocker on L1 target 
17) Remove blocker from target R1 
17.) Align on Tower of Power 1-2 using beam splitter A4 
18.) Put blocker on R1 target in order to check alignment on Tower of Power 3-4 -- WHAT TO DO IF DISALIGNED ? 
19.) Put camera target in front of camera. 
20.) Align on camera target using the Towers of Power and the cheat sheet. 
2x.) Turn off the alignment laser 
 
Notes:
Use a paper card to identify beams

==Hardware Subsystems==
===Overview===
=== Dichroic Pickoffs===

We have provided 3 sets of pickoff optics for use with CHAMP (the angle-of-incidence is 3 degrees). Each is designed with a 30' wedge and have been oriented with
thick part down (i.e., transmitted beams is bent downward by 13.7', which may be relevant for downstream combiners during alignment procedure).
All substrates have a broadband AR coating on the back-surface and the reflected light comes primarily from the front surface.

* Short-wave Pass (SWP):
These IR-grade Fused Silica substrates are coated with a dichroic coating to reflect K' band (2-2.3 microns) and to transmit JH bands (1.1-1.8 microns).

* [[Media:omega_swp.pdf]]: Performance of Shortwave Pass Dichroic (Omega)

%BR%

* Long-wave Pass (LWP):

These Calcium Fluoride substrates are coated with a dichroic coating to reflect JH bands (1.1-1.8 microns) and to transmit K' band (2-2.3 microns and longer for possible future experiments).

* [[Media:lwp_performance_001.pdf]]: Performance of Longwave Pass Dichroic (Omega)

%BR%

* Pickoffs Beam-splitters (BS):

These Calcium Fluoride beamsplitters were rejected from American Torch due to the coating not meeting specifications and the performance curves being proven unreliable. We believe the the coatings are about 50/50 at HK bands but are more like 75/25 (mostly transmitting) at J and beyond K band. This might prove useful in the future, but we do not expect these pickoff optics to be the best choice for most observers. Here is a measured transmission curve from the company, although we have not verified the accuracy yet:

Hardware card from National Instruments

===Beamsplitters===

The IR-grade Fused silica beamsplitters are 50% +/- 10% over the full JHK' bandpasses. The coatings were done by Omega Optical and
you can find the coating performance here. The angle of incidence is ~11.5 degrees.

* Four (4) f=450mm spherical mirrors for Tower of Power

* One (1) image slicer T1

* One (1) image slicer T2

* One (1) image slicer B1 [note: we are using the spare. the original B1 has some coating problems near apex and is put back as a backup/spare

* One (1) image slicer B2 [note: the backup spare B2 has slight problem where the bottom-right quad, B2d, is too large in one dimension. This means the pyramid will not fit in the holder. If one needs to use this backup, one will need to mill-out extra clearance in the holder]

Other things: TBDocumented, some card for camera electronics. zabar motors.

* One (1) motherboard for servers (compatible with mirkwood, champ -- one kept at CHARA, one at UM)

These Calcium Fluoride substrates are coated with a dichroic coating to reflect JH bands (1.1-1.8 microns) and to transmit K' band (2-2.3 microns and longer for possible future experiments).

* Pickoffs Beam-splitters (BS):

These Calcium Fluoride beamsplitters were rejected from American Torch due to the coating not meeting specifications and the performance curves being proven unreliable. We believe the the coatings are about 50/50 at HK bands but are more like 75/25 (mostly transmitting) at J and beyond K band. This might prove useful in the future, but we do not expect these pickoff optics to be the best choice for most observers. Here is a measured transmission curve from the company, although we have not verified the accuracy yet:

How to log into CHAMP for development.

1) Open three xterms, xterm1, xterm2, xterm3.

2) In xterm1: log as champdev@champ (192.168.3.136), pwd: *mIRC-Champ!

3) In xterm2: log as devel@192.168.3.143 (wolverine), pwd: *mIRC-Champ!

4) In xterm3: log as devel@192.168.3.143 (wolverine), pwd: *mIRC-Champ!

5) Open in a web browser: http://mirc-rpc02 (user: apc, pwd: apc ). Select Outlet/Control in the left bar. Use Immediate Turn On for CHAMP scanning PZTs, CHAMP Electronics and CHAMP picomotors (#1, 2, 4 in the list)

6) In xterm1,type:

cd ~/control/CHAMP/modtrig/

./modtrig (and press ENTER to stop it)

cd ../user

sudo ./astropci_usr 60000

7) In xterm2, type:

cd ~/CHAMP/gui/IRCam/

./IRCamMain.py

The IR Camera gui should launch.

Click Update DAQ in the FPA Tab.

Click Update Server in the FT Tab.

Click Config Camera in the FPA Tab.

Click Start Exposure in the top bar.

The camera now acquires frames.

8) In xterm 3, type:

cd ~/CHAMP/champGui/

./champGui.py

This will launch the main FT gui for CHAMP.

===Full Alignment===

1.) Turn on the CHAMP alignment laser 
2.) Align each beam on R1 target using A0 
3.) Align on L1 using A1 
4.) Put blocker on R1 (using L1/L2-target), so you don't see two spots 
5.) Align on R2 using A2 
6.) Put blocker on L1 (using the R1/2-target) 
7.) Align on target L2 using A3 
8.) Remove the current blocker from L2 for alignment of Towers of Power 
9.) Align on Towers of Power 3 and 4 using L1-L6 mirrors 
10.) Remove current blocker on L1 
11.) Put blocker on R1 (using R1/R2-target) 
12.) Put blocker on Towers of Power 3-4 
13.) Align on Towers of Power 1 and 2 using R1-R6 
14.) Put blocker on Towers of Power 1-2 
15.) Align Towers of Power 3-4 (L1-L6) --- DUPLICATE ? 
16.) Put blocker on L1 target 
17) Remove blocker from target R1 
17.) Align on Tower of Power 1-2 using beam splitter A4 
18.) Put blocker on R1 target in order to check alignment on Tower of Power 3-4 -- WHAT TO DO IF DISALIGNED ? 
19.) Put camera target in front of camera. 
20.) Align on camera target using the Towers of Power and the cheat sheet. 
2x.) Turn off the alignment laser 
 
Notes:
Use a paper card to identify beams

===Overview===
=== Dichroic Pickoffs===

We have provided 3 sets of pickoff optics for use with CHAMP (the angle-of-incidence is 3 degrees). Each is designed with a 30' wedge and have been oriented with
thick part down (i.e., transmitted beams is bent downward by 13.7', which may be relevant for downstream combiners during alignment procedure).
All substrates have a broadband AR coating on the back-surface and the reflected light comes primarily from the front surface.

* Short-wave Pass (SWP):
These IR-grade Fused Silica substrates are coated with a dichroic coating to reflect K' band (2-2.3 microns) and to transmit JH bands (1.1-1.8 microns).

We have provided 3 sets of pickoff optics for use with CHAMP (the angle-of-incidence is 3 degrees). Each is designed with a 30' wedge and have been oriented with
thick part down (i.e., transmitted beams is bent downward by 13.7', which may be relevant for downstream combiners during alignment procedure).
All substrates have a broadband AR coating on the back-surface and the reflected light comes primarily from the front surface.

* Short-wave Pass (SWP):
These IR-grade Fused Silica substrates are coated with a dichroic coating to reflect K' band (2-2.3 microns) and to transmit JH bands (1.1-1.8 microns).

* Long-wave Pass (LWP):

These Calcium Fluoride substrates are coated with a dichroic coating to reflect JH bands (1.1-1.8 microns) and to transmit K' band (2-2.3 microns and longer for possible future experiments).

* Pickoffs Beam-splitters (BS):

These Calcium Fluoride beamsplitters were rejected from American Torch due to the coating not meeting specifications and the performance curves being proven unreliable. We believe the the coatings are about 50/50 at HK bands but are more like 75/25 (mostly transmitting) at J and beyond K band. This might prove useful in the future, but we do not expect these pickoff optics to be the best choice for most observers. Here is a measured transmission curve from the company, although we have not verified the accuracy yet:

The IR-grade Fused silica beamsplitters are 50% +/- 10% over the full JHK' bandpasses. The coatings were done by Omega Optical and
you can find the coating performance here. The angle of incidence is ~11.5 degrees.
