簡介
EXVC
為了解決 X 射線通量對於探測器和處理 X 射線光譜的電子元件來說都過高的應用問題，Amptek開發了一個「准直器套件」來准直初級 X 射線束。 該系統由EXVC准直器外殼組成，可在 X-123 的1.5英寸延長管上滑動。
EXVC 准直器外殼最多可容納兩個鎢（W）准直器片，這些準直器片被放置在探測器前面的接口支架內。 通過選擇適當的鎢准直器片，用戶可以減少入射的 X 射線通量，並允許探測器和電子元件處理 X 射線光譜。 Amptek提供了七種不同的鎢准直器片，它們有不同尺寸的孔，適用於廣泛的應用。

In order to accommodate applications where the X-ray flux is too high for both the detector and the electronics that process the X-ray spectrum, we have developed a “Collimator Kit” to collimate the primary X-ray beam. This system is comprised of the EXVC Collimator Housing which slides over the 1.5 inch extender of the X-123.
The EXVC Collimator Housing can accommodate up to two Tungsten (W) collimator disks that are placed inside a bayonet holder in front of the detector. By selecting the appropriate Tungsten collimator disks, the user can reduce the incoming X-ray flux and allow the detector and electronics to process the X-ray spectrum. Seven different Tungsten collimator disks are provided with different size holes in order to allow for a wide range of applications.
The EXVC Collimator Housing is made of stainless steel and can also be used inside a vacuum chamber.
EXVC Collimator Kit Mechanical Dimensions. All dimensions in inches unless except as noted.
The EXVC Collimator Kit Includes:
- Stainless steel collimator housing
- Brass Spacer
- Tripod and mounting plate (included when ordering for use with standard 1.5 inch extender box)
- Laser pointer
- 5 Tungsten (W) Collimator disks:
- 1 mm thick with 25 µm hole
- 1 mm thick with 50 µm hole
- 2 mm thick with 400 µm hole
- 2 mm thick with 1000 µm hole
- 2 mm thick with 2000 µm hole
All Tungsten disks are made of alloy HD17 (90% W, 6% Ni, 4% Cu).
All Tungsten disks and spacers have a diameter of 0.625 inches.
Optional: EXVC-W-SPACER
This Tungsten (W) Spacer /Collimator is 36 mm thick with a 300 µm hole. It is designed to stop and collimate x-rays greater than 150 keV that are produced from high energy tubes.
