X射線管
X-Ray Tube 型號:Mini-X2-
Mini-X2 是一個微型 X 射線管系統,包括 X 射線管、電源、控制電子器件和與電腦的 USB 通信。 它針對緊湊型 X 射線螢光(XRF)應用進行了最佳化。 Mini-X2 通過接地陽極、USB 電流和電壓控制、簡單的准直器安裝方式以及操作簡便性簡化了 XRF 過程。
Mini-X2 由兩個元件組成:Mini-X2 X 射線管模組和 Mini-X2 控制器。 X 射線管模組包括射線管和高壓電源。有幾種不同的選項可供選擇:
最大高壓 50kV 70kV 最大功率 4W 10W 10W 陽極 Ag, Au, Rh, or W Ag, Au, Rh, or W Au, Rh, or W 控制器包括 USB 通信和軟體控制。 它可通過軟體進行配置,以支援任何 X 射線管模組。 一根 10 針軟排線將控制器和 X 射線管模組連接起來。 控制器介面包括 12 VDC 電源、用於命令和控制的 USB 以及帶有安全聯鎖和警告燈驅動程式的 AUX 介面。
Mini-X2 取代了 Amptek 以往的 Mini-X 產品系列。 X 射線管模組與以前的 Mini-X-OEM 類似。 控制器顯著改善了控制功能,包括軟體可配置性和更快的控制和回讀。 它採用完全不同的軟體介面,基於 Amptek 數位脈衝處理器使用的 FW6 協定。
所有 50kV 型號上都有方便安裝準直器或過濾器的螺紋。

此類損壞不在保修範圍內。 Amptek 的控制軟體會將功率限制在此曲線上。
如果命令的系統功率超出了功率限制,軟體將使用命令的 HV 並回滾電流以符合功率限制要求。

The Mini-X2 is a miniature X-ray tube system which includes the X-ray tube, the power supply, the control electronics, and the USB communications to the computer. It is optimized for compact X-ray fluorescence (XRF) applications.
The Mini-X2 consists of two components:
the Mini-X2 X-ray tube module and the Mini-X2 Controller. The X-ray tube module includes the tube and HVPS. Several different options are available:maxium HV 50kV 70kV maximum power 4W 10W 10W anode Ag, Au, Rh, or W Ag, Au, Rh, or W Au, Rh, or W The Controller includes the USB communications and software control. It can be configured, via software, to support any of the X-ray tube modules. A 10 pin flex cable connects the Controller and the X-ray tube module. Connections to the Controller are 12VDC power, USB for command and control, and an AUX connector with a safety inter- lock and a driver for a warning light.
The Mini-X2 is a replacement for Amptek’s previous Mini-X product family. The X-ray Tube Module is similar to the previous Mini-X-OEM. The Controller has significantly improved control features, including software configurability and faster control and readback. It utilizes a completely different software interface, based upon the FW6 protocol used with Amptek’s digital pulse processors.
Convenient threads for attaching collimators or filters are available on all 50kV models.Features

- 10 to 50 kV or 35 to 70 kV
- 5 to 200 µA (See isopower curves)
- Ag, Rh, Au, or W Target (Ag not available in 70kV)

Figure 2. Mini-X2 Isopower.
The current and voltage must be set in accordance with this curve or the Mini-X2 may be severely damaged. Damage of this kind is not covered under warranty. Amptek’s control software limits the power to this curve. If one commands the system to a power exceeding the power limit, the software will use the commanded HV and rollback the current to meet the power limit. Note that the curves differ based on the tube.
