Where Can I Find Diodes for Line-Shaped Beams in Soft X-Ray Experiments?

In summary, the speaker has successfully tested their read-out and data acquisition electronics for the Moxtek XPIN-XT Detector, achieving an energy resolution better than 300eV (@8keV) at high counts per second. They are now looking for diodes with a specific geometry for line-shaped beams and are seeking recommendations for a manufacturer. They have considered using scintillators or multiple diodes, but have concerns about achieving the desired energy resolution.

I have successfully tested my read-out & data acquisition electronics for the Moxtek XPIN-XT Detector. I cooled the PIN diode below -30°C and found an energy resolution better than 300eV (@8keV) up to 50k cts/sec.
Right now I am looking for diodes for line-shaped beams, i.e. about 14mm x 2 to 3mm active area. In the past there was a Si-PIN detector out (PF2400, also from Moxtek) which could be used for SAXS and XRD experiments, but is not longer available.
Can anyone help me to find a manufacturer of those PIN or SDD diodes with the above geometry?

Thanks

I'm not sure but you may get some good responses in the High Energy, Nuclear, Particle Physics forum. I'll report this post and see what the mentors think.

8 keV is not the typical high-energy range, but let's try.

Would scintillators be an alternative? Or multiple diodes?

I am not sure if scintillators are an alternative, as we want to achieve an energy resolution of approx. 300eV (to separate Cu Ka from Kb). Multiple diodes are in considaration.
 

1. What is a photodiode for soft x-ray?

A photodiode for soft x-ray is a specialized type of photodetector that is designed to detect and measure soft x-ray radiation. It is made up of a semiconductor material, such as silicon, that is sensitive to soft x-rays and converts them into electrical signals.

2. How does a photodiode for soft x-ray work?

The photodiode works by utilizing the photoelectric effect, in which the incoming soft x-ray radiation knocks electrons off of the semiconductor material, creating an electric current. This current is then amplified and measured to determine the intensity of the soft x-rays.

3. What are the advantages of using a photodiode for soft x-ray?

One major advantage is its high sensitivity to soft x-ray radiation, making it an ideal detector for low-intensity measurements. It also has a fast response time and can operate in a wide range of temperatures. Additionally, it is a compact and cost-effective option compared to other types of soft x-ray detectors.

4. What applications can a photodiode for soft x-ray be used for?

A photodiode for soft x-ray has a wide range of applications in fields such as medical imaging, material analysis, and environmental monitoring. It can also be used in research and development for studying the properties of soft x-ray radiation and its interaction with matter.

5. How do I choose the right photodiode for soft x-ray for my application?

When selecting a photodiode for soft x-ray, it is important to consider factors such as the wavelength range, sensitivity, response time, and packaging options. You should also consider the specific requirements of your application and consult with a specialist to determine the best option for your needs.
