Setting up a Flash X-ray experiment

6 Nov 2024 | Flash X-ray systems

Follow these steps to set up your flash X-ray experiment

The same steps apply for all Scandiflash FXR systems

Step 1: Prepare your X-ray tubes

Performing routine service or maintenance like a quick anode and cathode exchange on a flash X-ray tube requires venting the tube. The easiest method for preparing your X-ray tubes is to mount them on the RPS30 Service Station – it’s a hands-on workstation. It only takes seconds, and then you’re ready to quickly configure and service your tubes. Depending upon your experiment, you can swap out anodes and cathodes to suit your needs. And if you use the RPS30 Service Station, you’ll gain not only the efficiency of having the right tools and parts at your fingertips, you’ll also benefit from the turbomolecular pump that allows you to rapidly establish the necessary high vacuum in up to four Flash X-ray tubes individually or simultaneously before activating each tubes’ integrated ion pump.

And for even more flexibility, get the IPPS30 Ion Pump Power Supply – a stand-alone power supply to maintain the ideal high vacuum in your flash X-ray tubes – great for storage!

Note that our MAT sources do not require pre-pumping.  Read more about our Multi-anode tubes and our Cinematic Imaging Detector.

Step 2: Place your pulser

Move your pulser into the desired position for your experiment. The primary difference between each of our flash X-ray systems is in the pulser. From our debris and plastics penetrating pulser, the PG150, to our most heavy material penetrating pulser, the PG1200, Scandiflash pulsers are modified Marx surge generators. Our pulser tanks are precision-built and pressurized to improve insulation and control over spark gap switch breakdown voltage.

Step 3: Place your flash X-ray tube

Now you need to place your X-ray tube or tubes into position. This is where you’ll appreciate the extreme mobility of Scandiflash FXR tubes. Even our largest tubes can be easily handled by one peron.

If you haven’t already, you can finally say goodbye to SF6! It’s time to revolutionize your SF6 system with a breath of fresh air and enjoy the science of simplicity.
Say farewell to the days of complicated insulating gases and wave hello to our cleaner, simpler, and safer pressurized air system for your flash X-ray tubes.

Tip: If you want to speed things up a bit, you can set up your system without having the X-ray tube pumped down to high vacuum. Simply position the tube then continue with the following steps while pumping down the tube according to step 1 above.

Step 4: Connect the cable between pulser and cabinet

Now pull the cable set from the control cabinet to the pulser and it’s time to begin connecting all fittings to both the cabinet and pulser. Remember, fittings need to be firm but only finger tight. Do not over tighten the fittings.

Scandiflash cables are delivered as pre-bundled sets and are wound onto easy-to-handle cable spools.

Tip: If you want to test connections and timing of your system at this point, you can use the resistive load supplied with each pulser. 

 

Step 5: Connect the ion pump cable

Now connect the ion pump cable between the cabinet and the X-ray tube. This supplies the necessary power to keep the ion pump continuously actvated and maintain the pristine high vacuum. 

Tip: Continuous activation of the ion pump protects your tube from contamination. This is the ideal state for both storage and during experimentation.

Step 6: Connect the high voltage cable

Now you’re ready to connect the high voltage cable between the cabinet and the X-ray tube. Remember to finger-tighten only.

Step 7: Place your detector to capture the dynamic event

You’re nearly ready to run your experiment! Whether you are using a Single Image Detector or a Cinematic Imaging Detector, now it’s time to place your image detector so that it’s positioned to capture the dynamic event.

When positioning your image detector, it’s important to consider the distance between your test subject and the detector. The closer the subject is to the detector, the sharper the captured image. However, in scenarios dealing with subjects that rupture or create debris, there is a higher risk of damaging the detector when it is too close to the subject.

And when you need to capture multiple dynamic moments in time at a single fixed location, you can unleash the power of high-speed X-ray cinematography with CID – our Cinematic Imaging Detector. Our engineers have perfected and combined the necessary core elements while wrapping them up in a flexible and highly functional housing to provide you with a seamless solution that enhances your research.

Step 8: Flash your system to get the image

After you’ve followed all necessary safety protocols, it’s time to flash your system and see what’s happening inside your dynamic event!
