1. A container for producing radioisotopes by irradiation of a precursor material, the container comprising: a metal jacket of integral construction, the metal jacket having a symmetry of revolution about an axis, and having from top to bottom(i) an upper portion being open and having a conical shape, the opening of the cone being oriented upwards,(ii) a first cylindrical portion connected to the upper portion,(iii) a thin wall cylindrical section connected to the first cylindrical portion,(iv) a second cylindrical portion connected to the thin wall cylindrical section, and(v) a dome connected to the second cylindrical portion,the thin wall cylindrical section having a first thickness between 5 μm and 100 μm, the first and second cylindrical section and the dome having a second thickness larger than 100 μm. 2. The container as claimed in claim 1, wherein thin wall cylindrical section has an outside diameter between 4 mm and 100 mm. 3. The container as claimed in claim 1, wherein the container is at least partially made from at least one of nickel, titanium, niobium, tantalum, iron, chromium, cobalt or a stainless steel. 4. A method for obtaining a container as claimed in claim 1, the method comprising:providing a matrix;electrodepositing on the matrix a thickness of a metallic material, until a first thickness between 5 μm and 100 μm is obtained;masking a fraction of a surface of the matrix;electrodepositing on an unmasked section until a thickness larger than 100 μm is obtained;removing the matrix; andobtaining the container as claimed in claim 1. 5. The method as claimed in claim 4, wherein the matrix is removed by dissolution. 6. A target assembly for producing radioisotopes, including:a container as claimed in claim 1;a holding tube including at one end a threaded portion; anda ring including a suitable interior thread, the holding tube and the ring being configured to encase the container. 7. The target assembly as claimed in claim 6, wherein the container has an end having a conical shape, a base of the cone being oriented toward an exterior of the container, the holding tube has a conical end congruent with the end of the container, and the ring has a conical end congruent with the end of the container. 8. The target assembly as claimed in claim 6, wherein the holding tube and the container are mounted so as to be able to rotate about an axis, and the target assembly includes a motor arranged to make the holding tube and the container rotate. 9. The target assembly as claimed claim 6, further including a cooling tube placed inside the container and arranged to allow a cooling liquid to flow. 10. The target assembly as claimed in claim 9, wherein the cooling tube includes a cooling head that has a recess on a portion of a periphery of the cooling head, the recess to give incident beam a longer path in a precursor liquid.
