Abstract

A pressure chamber has a chamber wall. The chamber wall includes a sensor integrated within the chamber wall, wherein the sensor integrated in the chamber wall comprises defects. A method of determining an effect of pressure on a material is further described. The method includes applying pressure to a material within a pressure chamber and to a pressure chamber wall of the pressure chamber, where the pressure chamber wall has defects. A signal from the defects is sensed while the material and the pressure chamber wall are under pressure. A property of the material is determined based on the sensed signal.

First claim

What is claimed is:

1. A diamond anvil cell comprising a diamond culet, said diamond culet comprising a sensor integrated therein, wherein said sensor integrated in said diamond culet comprises at least one diamond crystal defect, and
wherein said at least one diamond crystal defect is a nitrogen-vacancy (NV) atomic defect in which two adjacent carbon atoms are replaced by a nitrogen atom and a lattice vacancy.

2. The diamond anvil cell according to claim 1 , wherein said sensor integrated in said diamond culet is at least one of a pressure sensor, a temperature sensor, a sensor for use in measuring magnetic fields from samples under pressure, a sensor for use in measuring electric fields from samples under pressure, a sensor for use in determining stress in a high pressure sample chamber, or a sensor for use in determining elastic and/or plastic deformations of a material.

3. A pressure device comprising:
a pressure chamber having a chamber wall, said chamber wall comprising a sensor integrated within said chamber wall;
an electromagnetic radiation source arranged to provide electromagnetic radiation to the defects:
a detector arranged to detect electromagnetic radiation from the defects; and
a processor controller arranged to control the electromagnetic radiation source to provide electromagnetic radiation to the defects, and to receive a signal from the detector based on electromagnetic radiation detected from defects,
wherein said sensor integrated in said chamber wall comprises defects.

4. The pressure device according to claim 3 , wherein said sensor integrated in said chamber wall is at least one of a pressure sensor, a temperature sensor, a sensor for use in measuring magnetic fields from samples under pressure, a sensor for use in measuring electric fields from samples under pressure, a sensor for use in determining stress gradients of a material in the pressure chamber, or a sensor for use in determining elastic and/or plastic deformations of a material.

5. The pressure device according to claim 3 , wherein said defects comprise optical defects.

6. The pressure device according to claim 3 , wherein said chamber wall comprises a diamond culet, and said defects comprise diamond crystal defects.

7. The pressure device according to claim 6 , wherein the NV atomic defects are formed by at least one of nitrogen implantation, growth of diamond containing nitrogen, or electron irradiation.

8. The pressure device according to claim 3 , wherein the sensor is arranged to sense properties of a material within the pressure chamber caused by a pressure within the pressure chamber.

9. The pressure device according to claim 3 , wherein the processor controller is configured to determine a property of a material within the pressure chamber caused by a pressure within the pressure chamber.

10. The pressure device according to claim 3 , further comprising:
a radio frequency (RF) source arranged to provide an RF magnetic field to the defects.

11. The pressure device according to claim 10 , wherein the processor controller is arranged to control the electromagnetic radiation source and the RF source to perform at least one of optically detected magnetic resonance measurements, quantum coherence measurements or depopulation measurements.

12. The pressure device according to claim 10 , wherein the processor controller is arranged to control the electromagnetic radiation source and the RF source to perform wide field measurements.

13. The pressure device of claim 3 , wherein the chamber wall includes a first portion comprising the defects, and a second portion comprising a gasket material contacting the first portion.

14. A pressure device comprising:
a pressure chamber having a chamber wall, said chamber wall comprising a sensor integrated within said chamber wall, wherein said sensor integrated in said chamber wall comprises defects
wherein said chamber wall comprises a diamond culet, and said defects comprise diamond crystal defects, and
wherein said diamond crystal defects are nitrogen-vacancy (NV) atomic defects in which two adjacent carbon atoms are replaced by a nitrogen atom and a lattice vacancy.

15. A pressure device comprising:
a pressure chamber having a chamber wall, said chamber wall comprising a sensor integrated within said chamber wall,
wherein said sensor integrated in said chamber wall comprises defects, and
wherein the chamber wall comprises silicon carbide and said defects comprise silicon carbide atomic defects.

16. A pressure device comprising:
a pressure chamber having a chamber wall, said chamber wall comprising a sensor integrated within said chamber wall,
wherein said sensor integrated in said chamber wall comprises defects,
wherein the chamber wall includes a first portion comprising the defects, and a second portion comprising a gasket material contacting the first portion, and
wherein the first portion is part of a diamond material, and further comprising a conducting material, and an insulating material disposed between the gasket material and the conducting material.
