Ref : [MH20M]

The MH20M motorized EDM has been designed to drill the tiny holes in any conducting gasket material that the diamond anvil cells (DAC) operation requires.

Fast drilling, high hole shape quality, high accuracy in centering and very easy operation make the MH20 the best tool to prepare the gaskets used in high pressure physics.

Features :

Drilling diameter : from 20µm to 500µm. Centring accuracy : < 5µm. Drills in any conducting material : Stainless steel, rhenium Easy to operate Fast drilling : 40µm /minute for a 200µm hole in a stainless

steel gasket Possibility to change the polarisation and to tune both the

voltage and the current : to optimise drilling performances as a function of gasket material, thickness and hole diameter.

Centering microscope (x 400) Observation microscope (x 40) Motorized drilling : the voltage between the electrode and the

gasket feeds back to control the movement of the vertical table. Weight : 12 kg; Size : 19 cm wide., 33 cm deep., 42 cm high.

Principle of drilling. (Spark Erosion with wire)

An electrode [B], at high voltage, spark erodes ametallic gasket [C] immersed into a dielectric liquid(e.g. light oil).The electrode is fixed. The tank «gasket holder ‘[D]set on the vertical micro translation table [E], movesup automatically during drilling.

Other characteristics.Before drilling, the centering of gasket is done by themicro metric XY stage [F] (the rotating head [A] hasto be rotated by 90° into the centering position).The adjustable electrode holder [G] makes it veryeasy to install and adjust new electrodes.

NOTE : Manual drilling is also possible with themotorized MH20M.

Electrode holder TP1 for MH20 spark eroder

BETSA®




Ref : [TP1]

The electrode holder TP1 has been designed to simplify drilling with the MH20 series spark eroder. It is standard on newer models of the MH20. This new holder can replace the existing holder on older MH20 . Mounting and adjustment of the new electrodes are very easy. Some aspects of drilling are simplified.

• Height adjustment of the electrode : 20mm. Continuous and soft by knob

• Electrodes :Required Type II Low cost electrode. Mounting or unmounting very easy

• Setting of the holder on MH20 : Can be done easily by the user.

Type II electrode

Stainless steel tube 1,6 mm Tungsten

50 mm 5 mm

Electrodes : 50µm ,80µm, 125 µm, 150 µm, 200 µm, 250 µm and needle.

Ref : [ELEC2]

Principle :

Ø 39

50Scale 1/2

The height of the electrode can be adjusted continuously so it is

not necessary (as it was in older versions of MH20) to lower the

gasket holder before rotating the drilling head.

The gasket holder can be fixed at the focus-plane of the

centering microscope and drilling can always start at this

position.

Gluing & Alignment Machine [GAM]

BETSA®




Ref : [GAM]Features• Centring accuracy : < 5µm.• Lighting: retro light using an ultra-bright LED.• Centering microscope* • Observation microscope*Size: 19 cm wide., 33 cm deep., 42 cm high.

Various additional options allow • Maintain your DAC to align your diamonds.• Add a mini resistive furnace to accelerate the glue

polymerization.• Measure your indented gasket thickness.• Load samples and ruby in your DAC.

* For the BETSA EDM users: both machines use the same optical components.

The Gluing & Alignment Machine [GAM] makes it easier the gluing of your diamonds on seats, on rockers and even on drilled diamonds. This machine can also measure the thickness of indented gaskets; control the MDAC alignment and the loading quality. It is made on the same mechanical structure than our EDM.

High accuracy in centering and very easy operation makes the GAM the best tool to prepare your high pressure experiments.

Example of use: diamond gluingThe [GAM] operation is similar to that of the [MH20M] EDM:1. Drive both the holding rod and the microscope to the reference point using the rotary head,

and the [GL100] XY stage.2- Put the diamond in place and align it using the second XY stage while looking through the

centering microscope.3- Rotate again the head by 90° to place the holding rod on the culet center.4- Move up the Z stage to press down the diamond, and glue it.

Other characteristics.The [GAM] positioning block can accept parts that are up to 20mm in height and 30mm in

diameter . The positioning is highly reproducible and can be adapted to receive parts of any otherDAC type .

Abrasive tool [PONC2] for electrode used in MH20 spark eroder

BETSA®




The abrasive tools have been designed in order to facilitate the repair (with emery-cloth) of used and worn MH20 spark- eroder electrodes.

The quality of repair does not depend on the dexterity of the user. There is no risk of destroying (bending or folding) the tungsten part of the electrode.


Ref : [PONC2]Electrode set:

- The tungsten top of the electrode is guided in a Ø500µm hole.

Top of the needle:

- The electrode is always perpendicular to emery cloth.

Erosion of electrode:

- About 10 to 20 seconds to repair an electrode.

Delivered with a set of 10 ultra-fine emery clothes (1200). Size of each sheet of emery cloth: 60 x 60 mm.

Motorization module MOTO1 for MH20 EDM

BETSA®




The MOTO1 module has been designed to permit the MH20 EDM to drill holes without being attended. This module can replace the micro Z stage installed on the MH20. (Hydraulic HYDRAP B or mechanical TBZ01). With the MOTO1 drilling is easier, faster, and better in quality.


Z –stage travel (manual or automatic) :> 400µm.Displacement by micrometer (manual or automatic) :250µm / turn.Automatic displacement:The motorized micrometer iscontrolled by the voltage between the electrode and the gasket to drill.Automatically reset to “zero” position after drilling.

Connection: by a 5 pin connector.Mounting: 3x M3 screws.

Weight: 750 gr.Dimensions : 128 mm, 87 mm,50 mm.

Advantages for gaskets drilling:

High quality and reproducibility.Fast drilling ( 40µm/min for drilling Ø 200µm stainlesssteel gasket).No operator action required during drilling. (exceptcentering of gasket).No risk of electrode damage by operator during drilling.Very easy to use.

Note : Upgrading the MH20 delivered since January 1998 needs no modification. The user can self-install the motorized module. No adjustment is necessary.For older models, the MH20 must be returned (3days) to BETSA® for refitting.

Raman Optical Transfer [BROT]

BETSA®




The BETSA® Raman Optical Transfer [BROT] has been designed for measuring Raman spectroscopic properties of materials at high pressure. Its small size and weight along with its fiber optics output to the spectrometer make "on site" measurements faster and easier.When equipped with an internal mini laser it functions as a "stand alone" instrument.


Ref : [BROT]

Features :

• Two different optical paths permit either to measure optical features or to visualize the sample without any loss. A flip mirror system permits to swap between these two paths.

• Optical transfer (microscope): Magnification 400. However, BETSA® can provide any other magnification upon request.

• Portable equipment : depending on options ; External sizes : 7,5 x 36,5 x 15 cm (3 x 14.5 x 6 “).

• The laser can be either provided by the user or added by BETSA® (see optional items below).

• The spectrometer can be either provided by the user or added by BETSA® (see optional items below).

Performances :

The BETSA Raman Optical Transfer was designed by BETSA and tested by Paul Loubeyre’s team (CEA). Fig. 1 shows an overview of a complete Raman measurement setup including a BROT.The BROT was designed and tested to be able to measure a Raman signal using a minimal Laser power. The laser power reaching the sample amounts of 83% of the incoming laser power. Using a Ø50µm core fiber optics, and a 300mm Shamrock-type Andorspectrometer, only 25mW of laser power are needed to make the 1st order Raman feature of silicon appear in 1s of integration time.
