TL2000 (thermoregulation unit): Integrated unit for thermoluminescence analysis
Code: TL2000
Category: TL
This instrument is the basic and fundamental element for any thermoluminescence analysis laboratory.
Using this technique, it is possible to date many samples from archeological sites, such as ceramics, brick, hearths, fire pits, kiln and smelter walls, heat treated flint or other heat-processed materials, sand and glass.
Integrated unit for thermoluminescence measures TL2000 is conceived to obtain very accurate and time- steady heating ramps, so it is possible to analyse the photonic emission at different temperatures of heated samples.
It is possible to manage the instrument trough a personal computer equipped with an IEEE-488 (GPIB) high performance parallel interface: a software to acquire and control data is available to allow photon emission measures.
TL2000 can be supplied with all the necessary to equip a complete thermoluminescence analysis laboratory, especially:
- vaccum oven to heat samples
- photomultiplier for photon counting
- high voltage power supply HiVo
- alpha particle counting system Calph
This instruments is already in use in many University and research centers in Italy and abroad:
- Università degli Studi di Milano
- Istituto Nazionale di Fisica della Materia (INFM)
- Università degli Studi di Torino
- Università degli Studi di Lecce
- Università degli Studi di Bari
- Pastis CNRSM di Brindisi
- Arcadia Tecnologie per i Beni Culturali di Milano
- Dipartimento di Conservazione e Restauro del Museo di Xian (Cina)
- Tubitak Marmara Research Institute, Gebze (Türkiye)
- Department of Archeology – National Museum and Library of Myanmar
Heating is obtained trough a heating resistive element. The temperature is measured trough a thermocouple type K.
The control of the power supplied from the heating element is a PID type: the error signal, obtained as difference between the reference temperature in the t moment and the actual temperature measured by the thermocouple, is differentiated and integrated. The three components (Proportional, Integral and Differential) are independently amplified (the amplified factors can be set by the user). By this way, it is possible to optimize the answer of the unit according different working conditions, having a very low difference form the heating theoretical profile.
The measure of the luminous intensity of the light emitted by the sample during the heating is achieved by a photon counting: for this, it is necessary to use a proper photomultiplier.
When the device is connected to a personal computer, it is possible to control TL2000 through the specific software, setting parameters and acquiring data. Communication between the device and the host computer is achieved through a GIPB interface with a dedicated protocol.
Besides, it is possible to manage TL2000 by the local keys on the frontal panel of the unit.
