The E-Shotgun, also referred to as the E-Gun, Northshore Sports Club CA-09,[1][2] or the PD-90 Advanced Coilgun, is a hand-held automatic 9-stage coilgun designed by Lei Fengqiao and manufactured by China North Industries Group Corp[3] in Xicheng District, Beijing, China (as well as "other technology teams"). In 2023, the CS/LW21 was commissioned by the Chinese government in order to "quell violent protests".[4]

Operating mechanism
editThe E-Shotgun uses a 20-cell, 80 volt, unbalanced lithium-ion polymer battery to supply up to roughly 16 kW of power to 9 solenoid drive coils.[5] Unlike many coilguns, the E-shotgun does not require a solenoid injector and instead pulls armatures directly from the magazine at the breach using the first coil. The CS/LW21 operates at medium voltage via a direct battery connection and does not use an inverter or capacitor charging system, which allows the system to charge rapidly to achieve a high rate of fire (up to 3000 rounds per minute).[citation needed] The 9 coils are shaped around a slot-profile barrel and are radially asymmetrical to accelerate large disk-shaped armatures at up to 45 m/s. The disk shaped armatures facilitate a large magazine capacity and high energy transfer due to their large mass, but tumble in flight due to their lack of stabilization.[6] The disks are also highly dependent on mass production and cannot be manufactured by users from readily available stock materials.[citation needed]
The shell of the weapon is manufactured from injection-molded polymer[5] and the coils are mass produced with high uniformity between prototypes, further increasing reliability.[citation needed]
