Abstract
The invention relates to an apparatus (1) for clamping flat samples (6), in particular pouch battery cells, for x-ray diffractometry, wherein the apparatus has a housing (2) having a sample holder (4), which has holding elements (5) that are able to be tensioned in relation to one another for clamping the sample (6), at least two x-ray windows (11a, 11b, 12) for letting in and out x-rays, and at least one first temperature control device (7) for controlling the temperature of the sample (6). At least one first temperature control device (7) is in each case attached to the holding elements (5), wherein the first temperature control devices (7) are thermally coupled to the housing (2), and the apparatus has at least one second temperature control device (9), which is configured to dissipate heat, which is output by the first temperature control device (7) to the housing (2), out of the housing (3) to the outside and/or to introduce heat from the outside into the housing (2).
Core Innovation
The invention relates to an apparatus for clamping flat samples, in particular pouch battery cells, for x-ray diffractometry. A housing having a sample holder provides holding elements that clamp the sample, with cutouts in the holding elements for guiding through the x-ray beam, and at least two x-ray windows for letting in and out x-rays while the sample is held in the clamping arrangement.
The apparatus controls the temperature of the sample using at least one first temperature control device that is thermally coupled to the housing. The apparatus additionally includes at least one second temperature control device that is configured to dissipate heat output by the first temperature control device out of the housing to the outside and/or to introduce heat from the outside into the housing.
The holding elements have a plate-shaped configuration with facing contact surfaces for clamping, and at least one first temperature control device is attached to the side of the holding element facing away from the respective contact surface. A spring mechanism tensions the holding elements in relation to one another.
Claims Coverage
The independent claim defines one core inventive apparatus concept with five inventive features.
Clamping flat pouch battery cells for x-ray diffractometry with plate-shaped holding elements and x-ray beam cutouts
An apparatus for clamping flat samples, in particular pouch battery cells, for x-ray diffractometry, wherein a housing has a sample holder with holding elements for clamping the sample, and cutouts are provided in each case in the holding elements for guiding through the x-ray beam.
At least two x-ray windows for in- and out-coupling x-rays
The apparatus includes at least two x-ray windows for letting in and out x-rays.
Two-stage temperature control with housing-thermally coupled first device
The apparatus has at least one first temperature control device for controlling the temperature of the sample, wherein the first temperature control device is thermally coupled to the housing.
Second temperature control device for heat dissipation and/or heat introduction at the housing
The apparatus has at least one second temperature control device configured to dissipate heat output by the first temperature control device to the housing out of the housing to the outside and/or to introduce heat from the outside into the housing.
Plate-shaped clamping elements with first temperature control device mounted on the opposite side and spring tensioning
The holding elements have a plate-shaped configuration and contact surfaces that face one another for clamping the sample, with in each case at least one first temperature control device being attached to the side of the holding element that faces away from the respective contact surface, and with a spring mechanism being provided for the tensioning of the holding elements in relation to one another.
Claim coverage centers on an x-ray diffractometry clamping apparatus that combines plate-shaped clamping holding elements with x-ray beam cutouts and at least two x-ray windows, and a two-stage temperature control architecture with a first temperature control device thermally coupled to the housing and a second temperature control device that dissipates heat out of or introduces heat into the housing, with spring-based tensioning of the holding elements.
