A user seeks to purchase a spherical metal vacuum chamber that ships internationally, possibly for a DIY project like a fusor or tokamak. The discussion highlights the challenges of building such equipment without expert guidance, emphasizing the importance of having a mentor with experience in high-voltage systems and vacuum technology. It is noted that while spherical vacuum chambers may exist, they are not commonly seen in laboratories due to practical concerns about stability and safety. The conversation also touches on the potential hazards associated with high-energy experiments, including radiation risks. Overall, the consensus suggests that acquiring a pre-made chamber is advisable for safety and practicality.
