Filters for use in dosimetry
Described is an optically stimulated luminescence (OSL) sensor comprising one or more cylindrical cup-shaped filters.
1. A device comprising:
an optically stimulated luminescence (OSL) sensor comprising:
a first filter having: a first base, a first substantially cylindrical wall extending from the first base, and a first recess surrounded by the first base and the first substantially cylindrical wall; and
an optically stimulated luminescent material (OSLM) mounted in a first recess of the first filter,
wherein the first filter comprises a first energy compensating material; and
wherein the OSL sensor has an exposed side where there is no filter covering the OSLM.
2. The device of claim 1 , wherein the first filter comprises aluminum.
3. The device of claim 1 , wherein the first filter comprises a plastic having metal particles dispersed therein.
4. The device of claim 1 , wherein the OSL sensor comprises one or more filter material layers located between the OSLM and the base of the first filter.
5. The device of claim 4 , wherein the OSL sensor comprises a converter material layer located between the OSLM and the first filter.
6. The device of claim 5 , wherein the first filter comprises aluminum.
7. The device of claim 1 , wherein the OSLM for the OSL sensor comprises an Al 2 O 3 :C material.
8. The device of claim 7 , wherein the Al 2 O 3 :C material has a grain size of 30 to 40 μm.
9. The device of claim 1 , wherein the first filter is a single piece.
10. A device comprising:
a dosimeter sled including one or more optically stimulated luminescence (OSL) sensors,
wherein the one or more of the OSL sensors each comprise an optically stimulated luminescent material (OSLM) mounted in a first cylindrical cup-shaped filter, and
wherein the first cylindrical cup-shaped filter comprises a first energy compensating material, wherein the one or more OSL sensors each comprise one or more filter material discs located between the OSLM and a base of the first cylindrical cup-shaped filter.
11. The device of claim 10 , wherein a first OSL sensor of the one or more OSL sensors comprises a converter material disc located between the OSLM and the first cylindrical cup-shaped filter.
12. A device comprising:
a dosimeter sled including one or more optically stimulated luminescence (OSL) sensors,
wherein the one or more of the OSL sensors each comprise an optically stimulated luminescent material (OSLM) mounted in a first cylindrical cup-shaped filter, and
wherein the first cylindrical cup-shaped filter comprises a first energy compensating material, wherein each OSL sensor has an exposed side where there is no filter covering the OSLM.
13. The device of claim 12 , wherein the first cylindrical cup-shaped filter comprises aluminum.
14. The device of claim 12 , wherein the first cylindrical cup-shaped filter comprises a plastic having metal particles dispersed therein.
15. The device of claim 12 , wherein the OSLM for each OSL sensor of the one or more OSL sensors comprises an Al 2 O 3 :C material.
16. The device of claim 15 , wherein the Al 2 O 3 :C material has a grain size of 30 to 40 μm.
17. The device of claim 12 , wherein the first cylindrical cup-shaped filter is a single piece.
