SBC Collect
1. SBCcollect main tab – Collect 
This screen is used to setup data collection parameters as well as monitor data acquisition progress. There are also fields for immediate controls of the beamline parameters. There is embedded tabbed frame with inspecting diffraction images, monitoring intensity changes during data collection and the editor for electronic notebook.
A.
ADSC Quantum 210r CCD X-ray Detector 
- 19BM beamline
- Verify that “Detector Mode” is either “Full” or “Bin”; choose desired mode using menu button in sbccollect main window.
- “Bin” mode is suitable for most experiments.
- “Full” mode should be used for samples with large unit cell lengths (> 350 Å) and when reflections are overlapped or otherwise not well separated spatially.
- If images are not being written to disk, contact your host immediately.
B.
ADSC Quantum 315 CCD X-ray Detector
- 19ID beamline
- Verify that “Detector Mode” is “Full”, “Hbin” or “Sbin”; choose desired mode using menu button in sbccollect main window.
- “Sbin” mode is suitable for most experiments.
- “Hbin” mode should be used for weakly diffracting samples.
- Full” mode should be used for samples with large unit cell lengths (> 450 Å) and when reflections are overlapped or otherwise not well separated spatially.
- If images are not being written to disk, contact your host immediately.
2. SBCcollect crystal alignment tab. 
This screen is used to setup data collection parameters as well as monitor data acquisition progress. There are also fields for immediate controls of the beamline parameters. There is embedded tabbed frame with inspecting diffraction images, monitoring intensity changes during data collection and the editor for electronic notebook.
3. Description of views used on the SBCcollect alignment tab. 
Presenting which cameras are serving which video signals on that tab. Two bottom video frames are showing high resolution images (visible is ~3um movement), one top frame is showing low resolution camera image (visible is ~20um movement).
4. SBCcollect diffraction image display. 
This screen is to manipulate and inspect diffraction images during data collection (the checkbox for “Auto updates”) as well as on existing images by using “Load file...” button to browse the directories and load the specified file. The operation on visible images are similar to those from the dtDisplay program. The middle mouse button click is providing full filename information on the bottom of the image (blue color), or when in “zoom in” mode returns to full view of the image. The middle mouse button and “drag&drop” is selecting the area of the image and zooming in on the selected area. To see information of the resolution, I/sigma, intensity, physical position on the detector as well as pixel coordinates – simply right-click on the interested point on the image. The bottom of the screen is providing the control of wighted controst as well as choosing the histogram range for intensities. There is also the button saving the active view of the diffraction image as a .jpg bitmap file.
5. SBCcollect sample mounting robot control tab. 
The main purpose is to provide user interface to operate the ID sample mounting robot. Controls include: starting/stopping the robot control system, choosing the sample from the list, editing information for the specified sample, mounting, dismounting the sample, aborting the robot operation, shutting down the robot, auto aligning the mounted sample, saving and loading the sample list to/from the .csv file.
6. SBCcollect electronic notebook tab. 
The purpose of that screen is to provide the ability to inspect and add notes about beamline operations for users as a timestamped documentation with automatic logging feature. The contents of the notebook is written to the fileSBCnotebook.txt into the directory to which user is collecting data.
7 . SBCcollect “Motion/Energy” tab. 
This screen is providing for users the access to individual motors involved in advanced beamline setup. It provides also the ability to automatically change the energy and afterwards manually optimize the position and intensity of the beam.
8. SBCcollect help screen. 
For each of the tab existing in SBCcollect there is separate help screen explaining meaning of each button, text-field or check box included in particular SBCcollect tab.

Fluorescence Scans using HKL3000

1. Check to make sure you are slightly above the peak energy of the element you wish to study, and mount a poor-quality crystal on goniostat. Do NOT use your best crystal; “junk” or twinned crystals are fine for these measurements.
2. Move to a directory where you intend to collect data for this project. Open a window, and type “HKL3000”.
3. Click on “Data Collection” button
4. Click on “Manual Control” button
5. Click on “Energy Scan” tab
6. Click and hold on “Scan” button; change to “Spectrum” mode
7. Choose element of interest via element button; default element is set to Se-K edge spectrum. Click “Spectrum” button at bottom of page.
8. A green window will pop up, requesting whether detector is properly setup. Since detector is permanently mounted on beamline, and software will automatically collect spectrum for you, just click “Continue”.
9. Results will indicate whether the element you are interested in is, indeed, found in sample – AND if other elements with lower energy absorption edges are also present.
10. Click and hold on “Spectrum” button, and switch back to “Scan” mode. Click “Scan” button at bottom of page to initiate measurement; you will again be queried about proper setup of detector (click “Continue”).
11. Allow entire fluorescence scan to be completely measured and collected.
12. If desired, spectrum and scan may both be labeled and/or printed, for future reference. Results from measurements will be written to directories named fluorescence_scan1 and fluorescence_scan2. These will be located in the directory from where you launched HKL3000.
