Patent ID: 7019307

Claim:
A particle detector comprising: a. a first delay line anode including an elongated first anode signal line, a first anode ground layer, and a first anode dielectric layer therebetween; the first delay line anode further including a first anode active area upon which particles impinge, the first anode active area containing at least a portion of the first anode signal line thereon; b. a second delay line anode including an elongated second anode signal line, a second anode ground layer, and a second anode dielectric layer therebetween; the second delay line anode further including a second anode active area which receives particles from the first anode active area, the second anode active area containing at least a portion of the second anode signal line thereon; wherein at least a portion of the second anode active area has the thickness of its second anode dielectric layer being identical to that of the first anode dielectric layer in the first anode active area.
