摘要

研究了四种具有低电离势的蒸汽:三乙胺(TEA)， N,N-二甲苯胺(DMA)， N,N-二乙胺(DEA)和四(二甲胺)乙烯(TMAEO)，以在比例计数器中产生可控量的激光诱导电离。DMA、DEA和TMAE在氮激光波长(337 nm)处产生大量电离，但TMAE已被证明难以控制。在337纳米处，TEA不会发生明显的电离，但初步试验表明，它也适合作为较短波长的播种剂。

Laser induced ionisation in proportional counters seeded with low ionisation potential vapours

Four vapours with low ionisation potentials: triethylamine (TEA), N,N-dimethylaniline (DMA), N,N-diethylaniline (DEA) and tetrakis (dimethylamino) ethylene (TMAEO) have been studied to produce controlled amounts of laser induced ionisation in proportional counters. DMA, DEA, and TMAE produce large amounts of ionisation at the nitrogen lase wavelength (337 nm) but TMAE has proved difficult to control. At 337 nm TEA does not ionise significantly but initial tests show that it also becomes suitable as a seeding agent at shorter wavelengths.
