The BX9-HT0 DAC is a diamond anvil cell for high temperature studies. In this model the sample pressure is generated by a gas membrane. It is a DAC with a high-performance heating method, using resistive heaters. One heater is mounted on the external body of the DAC and uses 200 W electrical power to reach sample temperatures up to 800 K. It is suggested to operate the cell inside a vacuum chamber, to prevent the oxidation of materials. Alternatively, to prevent oxidation, it is possible to use the cell in inert gas atmosphere.

The cell body material, with low thermal expansion, ensures that it can be used up to temperatures of 800 K. A K-type thermocouple mounted close to diamonds is used to control the temperature. A Rhenium gasket allows stable operation of DAC.

To realize the experiment at high temperature it is necessary to monitor the sample pressure to ensure that it do not drop as temperature ramps up. By a remote pressure device the membrane is under constant He gas pressure during the high temperature experiment, providing a continuous constant load, independent of temperature.

The BX9-L00 Diamond Anvil Cell possesses a large access angle with pressure generated by screws.

The cell is based on a reliable piston-cylinder design. It is provided with a symmetrical conical opening on both sides, suitable for powder and single-crystal X-ray diffraction and also for Raman spectroscopy. The BX9-L00 DAC has a 90 degree wide conical opening on both sides.

The piston-cylinder design, simple and reliable, permits a mechanical stability under high mechanical loads. Four screws, provided with conical spring washers, are used to increase the pressure. This pressure adjusting can be obtained without dismounting the cell from a holder.

The ruby lines detector or ruby fluorescent pressure measurement system is e compact box designed to collect the fluorescence emission of a small ruby chip placed inside the sample under pressure in the Diamond Anvil Cell (DAC).  Photoexcitation is provided by a Laser source at  532 nm.
A long working distance microscope, objective 20X, ensures high efficiency of fluorescence collection and good quality sample image. The fluorescence signal is sent through a dedicated optical fiber system  to a compact spectrometer. The side of the microscope has an optical entrance which allows, using the same microscope objective, to enlighten the sample for the visual observation. The ruby lines investigation employs a microscope technique requiring the addition of multiple optical instruments, the laser to excite the fluorescence of the ruby crystal, focusing optics and fiber optic for collection and trasmission of fluorescence. A PVM regulator permit to control lighting and laser parameters. The system is assembled with the spectrometer. The ruby lines are investigate to measure the pressure by a related software. RLW-001
The regulator of the power for the laser power and the sample lighting LED is inserted in a console fixed on the front of the microscope. The console can be separated for remote control.

Each part can sell separately related the customer or experiment’s needs.

The microscope can work in vertical (standard) or horizontal poisition.

The owner software dedicated to researchers useful to determine pressure value inside a dac sample room. Combined with our spectroscopy system Ruby Spectra Software 150 is destined to became our best solution to analyze pressure using ruby fluorescence peacks. It permit to calibrate and fit curve and analyze pressure inside cell. The measurement is performed through different calibrations of the R1 line shift, established in different ways depending upon pressure conditions and ranges.The fitting procedure allows you to fit the fluorescence ruby line R1 and R2 using two Lorentziano curves.

Once you optimized (maximized) the intensity of the fluorescence signal using the “Align” procedure you should write down the rough position of the two lines and then as input parameters for the fitting procedure.

Heater for DAC Cell is  equipped with a miniature resistive heating element for the simultaneous application of temperature

A reliable high-performance heating method using resistive heaters and a membrane driven diamond anvil cell (DAC) is realized. It enables almost perfect isobaric conditions for temperatures varying from 300K to 800K

One heater is mounted on the external body of DAC and use electrical power 200 W to achieve sample temperatures up to 800 K. If the optical access can permit is preferred to put the cell inside a vacuum chamber to prevent the oxidation of materials and grow up the temperature  and to sustain stable heating to over 800 K.

A K-type thermocouples mounted close to diamonds is used to control the temperature. The approach can be used for Raman spectroscopy and IR study at high pressures and temperatures. A Rhenium gasket material permits stable operation of DAC.

An external temperature control manage the parameters of current and temperature.

Cooling device for DAC cell  is a DAC cell  embodied in e large copper block, attached to the cold tip of a low vibration closed cycle cryostat systems providing a controlled low temperature vacuum environment, vacuum chamber is it. The cryostat, works on the closed helium circuit. Imdium material is a thin sheet placed for a termic contact from copper block and the cryostat tip. The sample is positioned on the sample holder (DAC cell) in good thermal contact with and surrounded by the vacuum. To change the sample, the cryostat must be warmed at room temperature, the vacuum released and the outer case and radiation shield removed.

A remote control for DAC is necessary to change the pressure inside the sample.

The vacuum chamber provide cryogenic environments for optical measurements for DAC cell. The designs combine the best optical access with the capability to operate in the temperature range 15 to 500 K. Benefits include a wide optical access for light collection measurements. Besides an optimized design provide an excellent optical access and a short space to permit to focalize beam with a objective 20mm WD. The large acceptance angle makes them ideal for light collection measurements (for example Raman studies). Optical measurements that cover a broad range of wavelengths may exceed the transmission band of a particular window material. All windows in the cooling devices are demountable. The present vacuum vessel can accommodate various types of diamond-anvil cells simply by changing the holder or different types of cold unit. High temperatures can be also used. The sample is located into the DAC. Changing the sample simply involves removing the cell, replacing the sample and inserting the cell back into the cryostat. The system can be adjusted in  X-Y-Z with manual or motorized stages how needs require.
