卤化铟被提议作为汞基低压放电灯的有效替代品，为了允许系统地研究含卤化铟的放电的等离子体特性，必须控制卤化铟密度的变化。这可以通过应用一种新设计的装置来实现，在该装置中实现了一个明确定义的冷点位置，冷点温度可以在50到350°C之间调节，而不会影响气体温度。通过将计算得到的蒸发InBr密度（利用蒸气压曲线）与白光吸收光谱测量得到的密度进行比较，证明了该装置的性能。
In order to allow for a systematic investigation of the plasma properties of discharges containing indium halides, which are proposed as an efficient alternative for mercury based low pressure discharge lamps, a controlled variation of the indium halide density is mandatory. This can be achieved by applying a newly designed setup in which a well-defined cold spot location is implemented and the cold spot temperature can be adjusted between 50 and 350 °C without influencing the gas temperature. The performance of the setup has been proved by comparing the calculated evaporated InBr density (using the vapor pressure curve) with the one measured via white light absorption spectroscopy.
