A significant difference between the designs of these high-current shunts from known (for example, described in ) is the use in them instead of a thin-walled (with a thickness of not more than 0.3 mm) high-resistance manganin
disk from which the drop in the pulsed voltage from the passage of a measured current pulse is taken, a disk of thickness of 1 to 2 mm from stainless steel 12X18H10T [10, 11].
Cabalin and Laserna  used pulsed laser deposition to coat silicon with manganin
. They produced multielemental maps to monitor the coating constituents.
The wire is made from alloys such as NiChrome or Manganin
; these have extremely low thermal coefficients of resistance (TCR) and excellent long-term stability.
we chose manganin
shunt that resistance is 500[mu][OMEGA].
pressure gauges record the voltage-time signals from which the pressure-time curves can be obtained through (1).
was developed about 1890 and is an alloy of copper, manganese, and nickel, nominally 84%, 12%, and 4%, respectively.
1) Standard resistor calibration: The 0.1 ohm standard resistor is a commercial, double-walled manganin
resistor (17) manufactured in 1913.
The structure of this shunt includes a manganin
measuring disk with a thickness [h.sub.s] [approximately equal to] 0.3 mm with an external diameter [D.sub.se] [approximately equal to] 80 mm, which determines the impulse resistance of the shunt, which is approximately [R.sub.S] [approximately equal to] 0.185 m[OHM] [+ or -] 1% [3, 7].
Resistance elements made from Manganin
alloy combine precision with a very low temperature coefficient of resistance (TCR) allowing operation over a typical temperature range from -40[degrees]C to +60[degrees]C.
If worrying about the effect of barometric pressure changes on the lattice structure of your Manganin
or Evanohm standard resistors is keeping you awake nights, help is on the way.
wire resistors developed by Thomas incorporated hermetically-sealed, double-walled enclosures, with the resistance element in thermal contact with the inner wall of the container to improve heat dissipation.
