  • Devices and methods for creating plasma channels for laser plasma acceleration
    Patent number: 11438999
    Abstract: This disclosure provides systems, methods, and apparatus related to devices and methods for creating hollow, near-hollow, and parabolic plasma channels. In one aspect, a device includes a block of material and a cooling system. The block of material defines a channel having a cylindrical shape and having a first open end and a second open end. An axis of the channel lies along a straight line. The block of material further defines a first gas port and a second gas port. The first gas port and the second gas port are in fluid communication with channel. The cooling system is operable to cool the channel to below the freezing point of a gas.
