TMS Vacuum Components

TMS is a young company with 10 years of experience in the design and manufacture of Precision Components for the Scientific / Analytical Industries, from Mass Spectrometers, Surface Electron Microscopy to Environmental Analysis and Semiconductor markets.

With our purpose built Clean Room and state of the art equipment were are able to meet your specification with out delay. Personal attention leads to effective feedback and quick reaction to change of specification.


TMS manufacture a wide range of filaments for Mass Spectrometers, other Electron Emission, Ion Guns, X-Ray Sources etc. Replacement filaments can also be provided.

Tungsten Filaments

Arising from our many years experience in manufacturing filaments TMS has designed and developed precision tooling which enables a high level of accuracy in aligning and tensioning of the filament wire. This assures a high standard of quality and repeatability

Mass Spectrometers

At TMS we manufacture a wide range of filaments for:

We can also provide replacement filaments.

TMS has many years of experience in manufacturing filaments and we can assure you of a high standard of quality and repeatability. We can supply filaments in various forms including wire and ribbon and materials we use include tungsten, rhenium and iridium.

Surface Electron Microscopy

We have invested a considerable amount of time and effort developing proprietary brazing techniques. TMS can offer you a wide range of cells for infra red or ultra violet environmental analysis.

The cells are normally made with a stainless steel or Kovar body with a copper filler tube brazed onto the side. The window materials used come from Sapphire, Calcium Floride, Quartz or Magnesium Flouride. We can make cells in Quartz or Sapphire with an optional graded seal filler tube to help the sealing.                              

Phosphor Screens

At TMS most of our Phosphor Screens are deposited on substrates using a  Brushing Technique of our own This will ensure an even and uniform layer.

We can supply many substrates:

  • Glass
  • Quartz, Fibre Optics
  • Filter Glass
  • View Ports
  • Lead Glass
  • Silicon Wafers to name a few
  • Also including Non Browning glass substrates which offer more resistance to high electron energies / x - rays.

For a more in depth look at the benefits and options then take a look at the website.


Applications for Phosphor Screens and Scintillators:

  • Scientific instruments
  • Mass Spectronomy
  • Electron Microscopy
  • X-Ray Detection
  • Image Intensifiers
  • Auger Spectrometers
  • IR & UV Detection

The benefit of our service is that scintillators have faster response times, high sensitivity and resolution optimised to the performance of a Photo Multipliers Tube.

Glass to Sapphire

Cells are usually made of stainless steel or a kovar body. The window materials can be Calcium Floride, Sapphire, Quartz or Magnesium Flouride.

Glass to Metal Seals

TMS has considerable amount of experience and knowledge in developing its range of proprietary brazing techniques. We can give you that experience to solve your glass to metal seal problems whatever your application.
