MCP (Microchannel Plate)
Hamamatsu Photonics 微通道板(Microchannel Plate,簡稱MCP),是一種二維平面的真空偵測器,通常被用來偵測帶電粒子,如電子或離子,也可以測得高速的中性粒子,以及在紫外光和X光範圍的光子。微通道板作用原理與光電倍增管和電子倍增管相似,首先是粒子或光子撞擊偵測器表面,產生了二次電子或光電子;再藉由電場加速,使電子再撞擊下一個表面,產生多次倍增的二次電子,使訊號放大。這表面是由高電阻的材料構成,為連續式的二次發射極 (dynode)。最後增強的電子訊號通常由一個陽極收集,或是打在磷光屏上顯像。
 
MCP is an electron multiplier that detects and multiplies electrons in two dimensions. MCP is also sensitive to ions, vacuum UV rays, X-rays and gamma rays and so can also be used as devices to detect their position and energy. To make MCP more convenient to use, we provide ready-to-use MCP assemblies complete with electrode leads.

MCP(Microchannel Plate)
MCP (microchannel plate) is a two-dimensional sensor that detects electrons, ions, vacuum UV rays, X-rays and gamma rays, and amplifies the detected signals. Circular and rectangular MCPs are available in various dimensions, including easy-to-use MCP assemblies with pre-mounted electrode leads and supports. These MCPs are widely used in many types of analytical equipment such as for "mass spectroscopy", "semiconductor inspection" and "surface analysis".
The MCP assemblies are available with three different readout devices to meet application needs. The devices are of: (1) single anode (electrical output signal measurement within effective region), (2) multianode (electrical output signal measurement corresponding to signal input positions), and (3) phosphor screen (optical imaging of output signal). Select the output device that best matches your application.
From one to three stage MCPs can be selected for the assembly to obtain necessary gain, allowing uses in the analog mode (the output signal is measured as a continuous electrical current) or the counting mode (the low level signal can be measured by a binary processing).
 
 

MCP(微通道板)是偵測在真空中的電子,離子,真空紫外光,X射線和γ射線,並放大檢測到的信號的二維傳感器。Hamamatsu 提供各種尺寸的圓形及方型的MCP(微通道板),包含易於安裝的MCP模組。這些MCP廣泛應用於許多類型的分析設備,如“質譜分析”,“半導體檢測”和“表面分析”。

MCP組件提供三種不同的讀取裝置,以滿足應用需求;分別為器件有:(1)單陽極(有效區域內的電輸出信號測量),(2)多節點(與信號輸入位置對應的電氣輸出信號測量)和(3)熒光屏(輸出信號的光學成像)。
