Abstract

A device comprises a tube with a tube HTS solenoid, wherein a projectile in a sabot comprising a sabot HTS solenoid. A method comprises disposing a seed HTS crystal on a growing crystal in contact with an a-b plane of the seed HTS crystal to grow the growing crystal, wherein the a-b plane is perpendicular to a c-axis. A method comprises disposing a seed HTS crystal on a growing crystal in contact with a b-c plane of the seed HTS crystal to grow the growing crystal, wherein the b-c plane is perpendicular to an a-axis. A device comprises a reinforced HTS material in a graphene casing, wherein the HTS in the graphene casing includes a cooling channel and a return channel.

Claims (10)

1 . A device, comprising:

a hollow high temperature superconducting material (HTS) solenoid tube;

a hollow HTS solenoid sabot within the HTS solenoid tube; and

a projectile in the HTS solenoid sabot, wherein:

a high temperature superconducting material of the HTS solenoid tube and/or the HTS solenoid sabot comprises one or more of the following: a copper oxide material, a rare earth copper oxide material (RE)BCO, an iron arsenide material, an iron selenide material, a LaBaCuO material, a LaSrCuO material, a LaSrCaCuO material, a YBaCuO material, a BiSrCaCuO material, a TiBaCaCuO material, a HgBACaCuO material, and a HgTiBaCaCuO material; and

a mixed reinforcing fiber of the HTS solenoid tube and/or the HTS solenoid sabot includes a current conducting core fiber comprising Silicon Carbide (SiC) and a reinforcing material comprising Silicon Dioxide (SiO 2 ); and

wherein the HTS solenoid tube has a closed end and an open end, wherein the HTS solenoid sabot has a closed end and an open end, and wherein the HTS solenoid tube and/or the HTS solenoid sabot include a current source for maintaining a current to create magnetic fields with opposing polarities between the HTS solenoid tube and the HTS solenoid sabot to force the projectile to project out of the HTS solenoid tube.

2 . The device of claim 1 , wherein the HTS solenoid tube is a rifled HTS solenoid tube.

3 . The device of claim 1 , wherein the HTS solenoid sabot is an HTS solenoid coil sabot.

4 . The device of claim 1 , wherein the current conducting core fiber is coated, cladded and/or composited with the reinforcing material.
