| description | We have built and characterized a gaseous particle detector of the type “multiwire proportional chamber”,
known as MWPC. The detector consists of an electronic circuit inside a hermetically sealed acrylic box,
in an appropriate atmosphere of gas. Once the mechanical and electrical operation was verified, we
performed the characterization as a particle detector. We measured the characteristic curve, consisting
of the electrical charge collected at the electrodes, as function of applied voltage. Then we measured
the count rate, for muons from cosmic radiation, versus voltage, known as “Plateau curve”. These
measurements were performed with different mixtures of gases: 100%Air, 100% Ar, 100% CH4 and 90%
Ar+10% CH4 (P10). In the results we discuss the operation of the detector at different voltages, for these
gas mixtures. The best performance was obtained with the P10 mixture, for which, the detector works
in the proportional region, for voltages between 3700 V to 4000 V, with an optimal operating voltage of
3850 V. |

Se construyó y caracterizó un detector gaseoso de partículas tipo “cámara proporcional multialambres”, conocida por sus siglas en inglés como MWPC. El detector consta de un circuito electrónico dentro de una caja hermética de acrílico en una atmósfera de gas apropiado. Una vez verificado su funcionamiento mecánico y eléctrico, se realizó la caracterización como detector de partículas. Se midió la curva característica, consistente en la carga eléctrica colectada en los electrodos, en función del voltaje aplicado. Luego se midió la curva de conteo de muones provenientes de la radiación cósmica en función del voltaje, conocida como “curva plateau”. Las mediciones se realizaron con diferentes mezclas de gases: 100% Aire, 100% Ar, 100% CH4 y 90%Ar + 10% CH4 (P10).En los resultados se discute el funcionamiento del detector para distintos voltajes, con estas mezclas de gas. El mejor desempeño fue obtenido con la mezcla P10, para la cual el detector funciona en la región proporcional, para voltajes entre 3700 V y 4000 V, con un voltaje óptimo de operación de 3850 V.
