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。

圖 2.Mini-X2 等功率。 電流和電壓必須根據此曲線設置,否則 Mini-X2 可能會遭到嚴重損壞。
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。
請注意,曲線因射線管而異。

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.

Output Spectrum with silver (Ag) target (left) and gold (Au) target (right). These were measured using a 1 mm thick CdTe detector located 1 meter from the Mini-X2 with a 1 mm pinhole collimator (made from tungsten) in front of the detector.
Applications
The Mini-X2 is based on the Newton Scientific Inc. miniature X-ray source. The Mini-X2 has replaced the Mini-X(orig); for information on the original Mini-X, see this link.

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.
