Microchannel Plates MCP

Microchannel Plate Detectors

Tectra has over ten years experience in the supply of Microchannel Plates (MCP) and MCP detectors / phosphor particle detectors. Benefiting from this experience tectra is now selling world wide its full range of MCPs and MCP based detectors.

For customers who have already designed their own MCP detector mount and need replacement microchannel plates, then tectra offers a complete range of very competitively priced nude standard MCPs and extended dynamic range MCPs (for high input currents MCPs). Our microchannel plates are available in all the well used standard circular OD formats e.g 12, 18, 25, 33, 50 and 87mm (MCP specifications). In addition we are also able to offer a customization service to bring you the MCP size that you need.

However our forte lies in the wide variety of mounted MCP configurations that we offer. Whether you require a single, double (Chevron) or Z stack resistance matched MCP coupled to a standard anode giving ~ 40ns time response or whether you need a fast anode for ion or electron time-of-flight detector with sub ns timing, then tectra has the off the shelf solution for you. Alternatively you may need to image or profile your ion/electron beam / soft x-ray / photon or other molecular or sub atomic particle. For these applications we offer MCPs together with high quality phosphor screens offering industry leading spatial resolution. When it comes to phosphors we offer the standard P20, P43 and P47 and have developed additional phosphors for fast timing requirements.

All the above combinations are available stand alone or flange mounted MCP detectors with the appropriate high voltage feedthroughs. Flange mounted versions can be supplied with or without viewport.

Joint our customers at major US and European research centers who have already experienced the quality and outstanding sales and application support that we offer.

* providing normal operating voltage is not exceeded.

MCP Micro-Channelplate Detectors

for in-vacuum mount and flange mounted.

Besides nude Microchannel Plates (MCP) we offer complete mounted MCPs as fast sub ns detectors for electron and ion time-of flight as well as MCP phosphor based imaging detectors for profiling of ion / electron beam / soft x-ray / photon or other molecular or sub atomic particles.

For high input currents our configurations are available with extended dynamic range MCPs. In addition the configurations are available with single, double and z stack MCP detectors. All the above combinations can be purchased stand alone or flange mounted with the appropriate high voltage feedthroughs.

So whether you need a phosphor image intensifier based MCP detector or a standard / fast anode MCP detector then Tectra has the off the shelf solution for you.

MCP detectors are offered with:

outer diameters 12, 18, 33, 50 and 87mm
as single MCP, Chevron and Z-Stack
large, regular and short mount
anode, fast anode* or Phosphor Screens**
ring or grid
flange mounted with or without viewport

** Phosphor screens can be:

Standard Phosphors:

P43 (green CCD read out)
P47 (blue PMT read out)

Fast Phosphors:

PB1 (blue PMT read out)
PG2 (green CCD read out)

* The Standard Anode has a time response of ~40ns. The Fast Anode
is available in 2 versions:

1. T Anode (Time of flight anode):

This fast Anode solution gives a time response Full Width at Half Maximum (FWHM) < 1ns and a rise time of <300ps. This is achieved as the Anode is impedance matched to 50 Ohm. This ensures that reflections in the time response signal are reduced to < 10% of maximum signal. The effect of reflections on the time response signal are therefore significantly reduced and ringing in the time response is reduced to < 10% after 1ns. Because the solution uses a SMA connector to acquire the signal it is suitable for a signal that is acquired at ground voltage only. This means that the MCP Microchannel Plate can not be biased at less than +2000V.

The T anode is currently available only for 33 and 50mm OD MCP detectors.

2. ET Anode (Electron Time of flight):

The ET anode gives a time response Full Width at Half Maximum (FWHM) < 1ns and a rise time of <300ps. This is achieved with a conical anode that is 50 Ohm impedance matched. The ET anode uses a N type connector that can be biased at up +3000V. It is therefore suitable for biasing the MCPinput up to +1000V and will allow for capacitive decoupling of the signal from the high voltage enabling electron time-of-flight applications.

The ET anode type MCP is available only with a flange mounted version (min CF-63) but for all common Microchannel Plate sizes with OD 18, 25, 33, 50 and 87mm.

MCP Detector data sheets

MCP detectors are offered as in-vacuum mounts and flange mounted. The in-vacuum mounts again are available as short mount, regular mount and as large mount. The flange mounted MCP detectors can be supplied mounted on a blank flange (MCP detector with anode) or mounted on a viewport flange (MCP detector with phosphor screen).

1. in-vacuum nount MCP detectors

The short mount and regular mount is very similar. The difference is just that the 3 leads of the short mount are bent towards the detector back side to minimise the detector envilop. The large mount detecor has an enlarged support plate with a lot of holes on the circumfence to ease mounting the detector.

See the data sheets here for short mount, regular mount and large mount.

2. flange mounted MCP detectors

Flange mounted MCP detectors are available on a blank flange or viewport flange. Besides CF flanges detectors can be mounted on ASA, ISO-K or other flanges on request. Blank flanges are generally used with metal anode. For MCP detectors with phosphor screen viewport flanges are selected.

See the data sheet here for MCP assembly on flange.

In the interests of continuous product development, specifications of the Microchannel Plates MCP or MCP Detectors are subject to change without notice.
